I had to re-tune my GT
I have been running my '10 GT with Brenspeed 93 tune which I love. Yesterday I noticed the car driving like stock with lower throttle response and much lower torque. When I got home today I downloaded the 93 tune again and everything is back to where it should be. The only thing I can think of is the last time I drove the car I had it up to 135 mph tacking it to around 6500 rpm. Could this of caused it to reset to stock?
