hi there i have been here before, i have a 6i90e built by tim king. i have since talking to you all had it gone through and the wave plates were put back in and tolerences checked, i put the trans back in and had a new cam and 3600 stall with 3:73 gears, at first when i would step on it it was like the car was pulling spark for some reason i thought it was fuel so i took it to alocal shop and they street tuned it. picked the car up and it ran fine for about three good drives then it would hesitate when stepping on it but only from about 2800 rpm. not from a dig or if i down shifted using paddle shifters it seems like what ever they did made it better but something else is got to be wrong. i know im not supposed to hammer it so that it kicks down with all its torque but is a super fine line if im just trying to speed up to merge or pass a car it will do a hesitate if im to aggressive. i would like to have you look at the data find out if its mechanical or tune oe module.

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
