Well something is wrong with my car after running it today. First pull 9psi base I ran 350 to the wheels. Running pretty lean at 13.5 to 1. Now it seems I may have to change out my dampener or/and my regulator. I don't know why I was just running lean as hell today. went as high as 18 to 1 and definitely heard some detonation. Not good. I hooked the Zem up today for the first time this was the second pull. loaded it up with 850CC injectors with duel filtration and went to pull and man it sounded like it was gonna blow up today not good. So I put ashspec chip back in and seems to run fine but still lean. My ? is would you need to create a custom map for the Zem and load it up before trying another pull?? I have never tuned a car before so I dont know what I am doing. Thanx for the heads up
