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.

6L90 5 to 4 downshift flare

I have attached a log of a 5 to 4 downshift and its flaring for a bit before dropping down to 4th. It also looks like the RPMs are dropping lower after the flare before settling where they should be in 4th gear.

I also attached my current tune file.

My tune is only for the 6L90 as im using the TCM-2650 with a Gen III LS. Everything else feels great in the shifting. I just cant figure this one out.
