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.

6l80 Rev match

We have a customer's car that has been in and out of our shop getting issues fixed from a previous shop. It's next visit this weekend is mainly for rev match downshifting. This customer is very picky on his rev match, has even gone as far to pay us to install a new TEHCM and zip kit. In previous visits we have attempted to get it to work. This G8 is 6l90LCC swapped. We have tried making the shift patterns match a G8, a CTS-V, and a 3500HD (OEM application for the 6l90LCC), all to no sucess. Could someone give some insight or try something to help us out? The previous shop has left us some tune grimlins on other cars, I'm guessing we havn't found this one.

2008 G8 1900 Maggie, FBO, cam, ZL1 converter, and 6l90LCC
