Met with Phil at the dyno yesterday to re-tune my 2013 ZL1. I had a flash on it from a known reputable online company and wasn't happy with the way the car was performing. Phil was very good at explaining what was going on and how the new calibrations vs old were effecting the cars performance.
We started the afternoon at 535whp and ended up at 556whp. AND this is also after a previous flash! Also I was happy with the TCM adjustments and thought the tranny was performing optimal, boy was I wrong.. Phil really made the shifts much much firmer to where it almost feels like my old GTR shifting.
Thanks again Phil and his team.
