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.

17 silverado 5.3

The truck is basically stock (volant cai/ exhaust) and I've messed with both the engine and trans tune quite a bit. it drives very well, although I'd like the truck to shift higher in the rpms but when i command high mph it works for a little bit. Then it gets strange and will hang before shifting. also has a harsh 3-2 downshift when using TUTD only

I haven't touched the maf, how does that look with the cai? is that affecting anything?

I've read through your site and have done some pressure and shift time tweaks. anything else you would recommend?
