Plugs and a tune
« on: July 01, 2015, 10:59:42 AM »
I bought the AEM Methanol kit and DDM's tune not long ago. I hope to have Dr. Dave install them sometime this month. I want to change my plugs before the tune as I have 35K miles on the engine. I have read several posts about different plugs, but believe the ACDelco 41-108 to be the best based on most responses. My question is concerning gapping the plugs - it's all over the book. I see .28/.32/.35/.44, etc. Which is the better gap for my application?

Pretty sure mine are gapped at .032 and I'm running 27psi on an EFR turbo. I haven't had any problems with the stock plugs that I replaced when I installed the turbo.
The road to success is always under construction.
