I know you guys are running times at the track, but I used my iPad for this. So question is how accurate are the obd2 sensors? I used the elm327. The 1/4 mile slacked as I ran out of real estate, but depending on accuracy this bone stock SHO does pretty good! At least in my opinion. I should be able to have my baseline dyno done Thursday, install tune, CAI t-stat, and plugs and another dyno run to see improvements!
