Has anyone see gains in MPH and ET making runs with the converter in locked veruses locked? Car is a 2013 Zl1 full weight with about 650 rwhp. Interested in trying a tune leaving the converter unlocked.
Unlocking 6L90 converter at the track...

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.
