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.

2011 Sierra 5.3

Hi,

Read the site, a lot of good info. Wondering on a tuning strategy. I currently have nice firm upshifts using added modifier (-.5), increased pressure (+30) and decreased time (*.75). I just kind of pulled these out of the air before I joined here and it feels good. I was wondering if it makes sense to just change the pressure and log shift time then "back" that into the tune. I've yet to work on downshifts but the 2+ gear downshifts need speeding up. Anyway, current tune attached.
