Just a RMM,short shifter and air filter, which neither of them should have an effect on what I was seeing. I also tried in Sport mode and all the way off to make sure it was possibly detecting the wheels slipping
Oh interesting, wouldn't have thought of trying sport mode. Yeah I'm wondering if is something to the fact that I have a catback exhaust like that guy I quoted in my orignal post.
Judging by Cobb's website for the OTS Stage 1 tunes for 91 vs 93 I saw it claimed only like 2-3% difference in torque increase over the 91 tune.
I'm sure the 93 is worth it more for the higher stages? Price of gas for me isn't a concern but I do prefer Shell gas and we only have one Shell station here and its highest octane is 91.
