Just checking in here to see the latest on the GM Stage 2. From my understanding you can't get just the sensors because the operating system is re-written to take advantage of the 3-bar sensors instead of 2.5 bars. If this is the case, the sensors without the bars are useless as you will still be subject to the 255 kpa limit and go into limp mode past 22 psi.

So having said that, the GM Stage 2 is a stepping stone to bigger and better things. We can hopefully tune this and boost above 22 psi without going into limp mode and get some more power but the real gains will be from big wheeling or a bigger turbo upgrade.

Is this the consensus?

Rather than a concensus, it seems to be the truth. In reading about this on this, as well as the Sol and Sky forums, and the HHR forum, there seems to be a laundry list of reasons for the 3 bar sensor. Yes, the GM tune is written to the 3 bar sensor but apparently for reasons other than just using those sensors. Liability, warranty, and performance were all issues. What those two Bosch 3 bar sensors will let OTHER tuners do is REALLY uncork the horsepower hiding in that tiny engine !!!! And for those that obtain the modified stock turbo LOOK THE HELL OUT !!!!!

Here is what is truly amazing. All this is being done with stock exhaust manifold (there is a hand built header available now), head work (noise is being made about that), bigger injectors, different cams, different valve springs to allow higher rpm (beyond 7500rpm, as if it is really even needed), BOV's, etc. Of course there are BIGGER turbos, better rods and pistons, and who knows what. One only has to realize that early Z06's had 405 horsepower and about 430 ft/lb torques, and some tuners are real close to get those sort of numbers out of 122 c.i. thing we have, and on pump gas. Crazy.

I hate those guys... I'd rather pay a couple extra bucks with Crate Engine Depot. At least they understand customer service.

Joe, The SOFA doesn't care you have to be on orders there, period. As a retiree you cannot use most of the base facilities, lodging and the air terminal are about the only exception. No commissary no exchange and the big one no gas station. Each country writes their own agrements, but most are written so that we have to use the economy to get anything.

It is true you can fill out forms and get the VAT back, but it is a long drawn out process intentionally

Thanks for the info. SOFA

-35c ouch, that has gotta suck. Programmer, did you get your kit in yet?

Just finally got my price quote today from the GM dealer (he emailed me a couple hours ago). $1134 CDN, and now finally available.

Thats what $934-935 US.

If you buy from a dealer here it's what $750 and at least an hour labor to install, 2 if they can get away with it. So if that is an installed price it's close if not, then you have a choice. Do it, or not. I think you will, and I hope you will.

Lyndon, I just sent you an e-mail. Something is seriously wrong with that amount.

lil goat · « **Reply #60 on:** December 24, 2008, 07:49:43 PM »

I think the big question is if Lyndon buys it somewhere else, like any one of the discounted suppliers, will the dealer in Canada install it for him. I know the local dealer here will, they did Chucks, but I am willing to bet lots of dealers won't unless you buy it from them. I know he won't need the tune part anyway, but if you pay for it you should at least have a copy to play with. Remember anything that ships to Canada, has to have a declared value, then they have to pay tax on the declared value. I would be happy to order a kit and ship it with a $20 declared value, just like I did my ECM when it was first tuned.

Boy do I have a story on this Dam tune for u Guys. But of cause it has to end first. And since a truck backed into my car today and it's now off to the body shop. Once I get it out and the Saturn dealership which installed the kit, fixes there f-up I will post for all to read. BUT FOR NOW since this is the second time in less than a year my car has been hit. (at least I wasn't in it this time.) I will go and cry myself to sleep.

OK so it's not that bad, i will post pics tomorrow. It was dark by the time I saw what happened. So will take pics tomorrow.(in the snow)(why not)

Start a new thread on your crunch. Sorry to hear that, what a bummer. Sounds like it happened at the dealer.

Hi
Im a Newbie to this forum and just purchased a 07 GXP Solstice.
Is this GM performance kit(stage II) purchased through my local GM dealer? How much is the cost of the reflash,new sensor/s and installation of the Performance kit is this one price meaning is there any additional costs?
I was planning to do the waste gate mod for the time being but if I do this kit I would need to put it back to the stock location correct? What about after the installation can I do the waste gate mod again or not advisable to do so?
Thanks for your help in advance and sorry for any stupid?'s

lil goat · « **Reply #64 on:** February 02, 2009, 02:34:23 AM »

It is installed by the dealer, you can buy it from the dealer for $650 I believe, or $550 from Crate Engine Depot. A dealer must install it, there have been a lot of different prices reported but it should be about $150 or so for the install. If you are going to do the tune I would leave the wastegate alone, it hasn't been tested with the GMPP tune yet that I have heard.

In my area 92 octane is the best at the BP station and everywhere else is 91.

tazz · « **Reply #70 on:** February 02, 2009, 05:02:24 PM »

So if im understanding correctly the GM stage II package is fully warrantied by GM so if something goes wrong because of the tuning they foot the bill? For this piece of mind it will cost at least $700 to $800 depending on where the kit is purchased from either crate engine depot or the dealer but in either case the dealer must install. The install should be around 1-2 hrs of chargable time so about $160 or so.
The wester's tune I would need to send my PCM off to be programmed and they would flash the PCM with all current GM updates and for any specific mods that I may have for around $400 @ Wester's Sales but if something were to go wrong GM will not warranty the problem correct?
So it will all boil down to if you feel comfortable not being warrantied by GM and wheather the extra $400 is worth the piece of mind or your willing to take your chances.
At this point for a stock GXP which tune will deliver the best performance for 92 octane fuel.
This vehicle is not my daily driver so if I need to be down a few days it's not a problem but I also dont want to blow my motor either.

lil goat · « **Reply #71 on:** February 03, 2009, 03:39:46 AM »

OK let me really confuse the issue, let me get up on my soap box THER IS NO SUCH THING AS A STAGE II kit, mainly because there never was a Stage I, the Stage II kit is for the Cobalt S/C, OK back down off my soap box. You can also install the Westers tune with HP Tuners, about $495 then Wester's emails you the tune and updates as needed, if you want to do the Wester's absolutly the best way to go, but adds $500 to the cost. By the way you do get a very nice perfomance monitor with the HP tuners as well, and there is a Pro version for $649 too. Now to really confuse the issue, if you buy the Wester's AND the GMPP, Wester's is doing a tune to take advantage of the different TMAP sensors used in the GMPP, so now you have really blown a lot of money but you have the best possible tune. GMPP+Install+Wester's+HPTuners = $550+$150+$395+$495 = $1590. And yes that is where I am going.

tazz · « **Reply #72 on:** February 03, 2009, 09:16:45 AM »

I think I understand and I could in if pressed for $$ do it in 2 stages meaning do the GMPP then do the Wester's to take advantage of the GMPP.
My next ? have Wester's said or shown how much of a improvement over the stock GMPP tune they can ring out? on a stock Solstice for the extra $$.
The reason i ask is that I nickled and dimed my last vehicle with power add ons when I could have just just spent x amount of $$ for almost the same out come or spent upgraded to a different larger Supercharger or Turbo setup that would have added way more power for about the same amount of $$ I spent.

Critterman · « **Reply #73 on:** February 03, 2009, 09:22:02 AM »

Tazz,
Talk to DeepBlueGXP, LilGoat, ChuckDoc, Spikey, Dark Tech, G0-N-DEAF and a few others that have been part of the test bed for Westers tune. They are putting down some fantastic numbers. I run around with most of those guys and the cars run and run hard, but they also drive well.

DeepBlueGXP · « **Reply #74 on:** February 03, 2009, 09:27:53 AM »

Westers Tune has provided the largest gain over other tunes for stock and the GMPP while maintaining great gas mileage.

Westers is currently in the test phase of the GMPP tune and an Automatic GXP. I'll read a manual GXP soon and work with Westers to improve that version also.

What lil-goat posted is the way to go. even if you dumped 2K++ in a larger turbo, you would still need a tune.
