i think is a boost adaptation issue because the car doesn't do than on the road , it seems to do this because a boost overshoot and sub-sequent wastegate duty cycle reduction.
i'm going to see if i can make it to the dyno tomorrow and i'll have some logs of the dyno runs and street runs so we all can compare.
BTW, did i mention my car is trapping 114.xx with 2.6 60' ?!?
And i'm getting some DR's on 17" wheels this weekend.....we'll see!
