Topic: Question on GMPP tune and CAI install

[bokrock]

I'm picking up my 08 Solstice GXP tomorrow and I am having the GMPP tune and GMPP CAI installed on Monday. The question is can I do them both at the same time or do I need to do the tune first and drive it for several cycles so it can relearn before installing the CAI ? The guy at our parts warehouse said to do that or it will throw a code and won't run as good ?

[Kelu]

GMPP CAI shouldn't throw you any CEL, stock tune or GMPP tune. Maybe I'm wrong, we don't have such things around here.

[elff]

You can do them at the same time with not worries

Aren't there any Pontiac owners on this site ! 
No really i'm just kidding, thanks for the info guys.

Make sure the dealer doing the work has done it before.
If they have not make sure they verify they actually downloaded the GMPP tune.

[bokrock]

Thanks, we have installed 2 of them, but never together at the same time with a CAI kit. When I ordered them from GM's warehouse the guy said to make sure not to do them at the same time, I never asked him for any info either he just said it like it was gospel. My tech can't understand why it would be a problem that's why I thought I would ask those with experience with these things.

I have always preach the TUNE 1st then everything else afterwards.
Also the the MAF is on the intake and is in a different location from the original intake vs the GMPP intake.
It may take a while for the GMPP tune to adjust itself, give it a few key cycles and if it does not improve take it back.
However I would just call your dealer and make them aware of what is happening.

Would the battery disconnect, the pull ecm fuse trick or fuel trim reset via DashHawk help make the relearn happen faster?

Don't put too much emphasis on relearning especially when adding oem gmpp parts, after you flash the car your power gains will be instantaneous.

there have been alot of people who claim the tune got better over key cycles, flash being one of them, supposedly the learn down maps are retained after the flash and they have to be erased through key cycles or the battery disconnect

om any event, it can't hurt to disconnect the battery and start from scratch after the tune

We dyno'd 4 cars with GMPP tunes on the same day.
Some had aftermarket CAI/IC Pipes other didn't
all cars were within 1hp of each other.

So the non stock IC Pipes and CAI don't hurt, but they also don't help

All this ecm relearning talk is really being blown out of proportion, the ecm is constantly learning no matter what, why do you think when its cold outside the boost drops and when its hot it goes back up? Install the mods, drive the car and enjoy, stop worrying about little stuff like this.

Amen Brother!!!
Although, I think I want you to tune my car

He shared everything he did for free in his thread. And it's open in the HPT forums too. Now we've heard that other tuners have access to more parameters using other tools, but I am not too sure how true that is.

[bokrock]

Nothing has been installed yet. So are you saying we should do the tune first and then do the CAI later ? or doesn't matter ?

It should not matter.

How do you make sure they verifiy they downloaded the GMPP?
Is it just a verbal confirmation or does it have to be documented it in someway?

[LatinVenom]

There is a specific file the dealer has to download.
We have had instances where the dealer actually just downloaded the original Tune.

[Sol Asylum]

I should not matter.

But you do matter Critter, you do matter.

[Critterman]

But you do matter Critter, you do matter.

LMAO - fixed it, thanks, but could have done with out the

[bokrock]

Well we installed the Tune, let the car run for 10-15 minutes with a couple of key cycles, then installed the CAI (Per GM recommendation). Everything went great, WOW..I could feel the difference wright away. I especially like the no lift shift feature ! Great fun  

[Kelu]

Nice to hear that, but this doesn't save you for posting pictures with your car, you might forgot this, but I didn't 

[bokrock]

Yeah I do have to work on that !

I'm sorry I still don't understand.  How does the customer "know" if the dealership downloads the GMPP tune or the original tune?  (I'm assuming by the orignial tune you're talking about the tune from the factory).  If the dealership doesn't give the customer documentation (and an work order invoice doesn't prove anything other than they charged you for service) the only way I can think that a customer would know for sure that the GMPP tune was installed was if they verified their DIC boost guage reads higher than it did before it was installed?

Not trying to be anal, but since I have the GMPP and have yet to have it installed I want to be able to verify that it was installed because this is the first I've heard of folks being charged for something they didn't get. I've been the victim of dealership scams and don't want to again.  For example; I called my local big box Chevy dealer and was told they had installed several GMPP kits, only to show up with it to make an appointment and be told by a service writer they wouldn't install it.  That was it, no explanation, and no referral to another dealership...until I asked.  Then I asked a salesman I'd been talking too about it and he said; oh, our  (sevice dept) doesn't like to install performance products they've had problems with in the past.  Not exactly confidence inspiring.

As far as I know there is no way for you to tell unless you watch the tech do it. But I can tell you from recent experience that you will know, both bye the seat of the pants and bye the boost gauge and bye the tire smoke !
Also, where did you buy the car from ? I know they don't sell Pontiac's anymore but they may still be there as a Buick-GMC dealer, if they are that's who I'd try first.
