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.

1-2 shift and TB blade closing by itself and timing being pulled

Hi, we have a built 6l90E the car is making 900whp...we are having a problem on the 1-2 shift with the TB wanting to close and timing being pulled..we have taken even all TM out of the 1-2 shift even and it still closes the blade some and cuts timing right before the shift, this makes the car fall on it faces in the 60ft.

Would you be able to take a look at the log and the tune in the car to let us know if it's the trans slipping that is causing the TB to close and timing being pulled or possible wheel spin/chatter ..we have everything turned off in traction control in the tune also.
