Message it... i was only running 16-18 psi of boost... for some reason or another my EVC won't let me get higher than 18 even though it's set at 1.5 bar (i'll have to recalibrate it i think). so, i figure it was probably making about 500-530 crank hp at that boost level. i was really there to tune my traction control system and not try and not necessarily get a great 1/4 mile time. it was a little bit harder than i expected. basically I was spinning my tires with every launch for about a second or two because i was dumping the clutch with 5 psi of boost by using the launch control feature. (best 60' was a 2.4 on normal street tires... Yokohama AVS Intermediates) i was trying to tune it so that i could just dump the clutch instead of riding it out like i usually do. i'm sure if i had just eased out the clutch i would have had much better times. i just want to get the damn thing adjusted right so i know exactly how much the racelogic system will help before i start the group buy. the great thing about the racelogic system is it's so adjustable and the bad thing about the system is IT'S SO DAMN ADJUSTABLE! LOL! there are literally 40-50 different things you can adjust... so, it might take me a while to figure it out.

anyways, i'm not too worried about the performance of my engine... yet. i just watched a video of my runs and noticed that my O2 sensors were pegged at 0.97-0.99v (majorly rich!) the whole way down the track, so i'll do some tuning later on with the SuperAFC, run 20-21 psi of boost, and maybe run drag radials and eventually hook up my NOS bottle in order to get my real 1/4 mile times.

aren't you coming down soon? we should definitely hang with Rob and Gyro when you come down.
