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.

Need Help with my 09 Sierra Denali Trans tune.

I have a 2009 SIerra Denali with the 6l80e transmission. The truck has a Texas speed VVT-1 Camshaft package, 1-7/8" Long Tubes, Exhaust and a Airaid CAI. I sent my stock tune file out to texas speed to get it retuned for their camshaft package and the shifting hasnt been right ever since. The shift from 1-2 has some bad flare at VERY low speeds, like it only acts up when your barely pushing the gas like in a parking lot of leaving someones driveway. and the shift from 4-5 has been acting wierd recently at normal everyday driving accelerations. it will sometimes act like it misses the 4-5 shift and over rev. Can anyone help me please!!!! I am going to upload my current HP tuners file. Thanks
