Hi fellas, was looking for some info to smooth out some roadblocks im hitting at the moment. Keeping it short the car is an fg xr8 with an aftermarket blower kit. Unfortunately I have to temporarily remove to pass an inspection. Anyway here's where im at -car was tuned when the kit was first put on with another flash tuner, which the original owner lost/kept -next owner re-tuned the car with a different flash tuner (xcal4) -I bought the car, have removed the kit and am now at the stage of hitting the back to stock tune button to get it running again now, 1) will my xcal4 have the stock tune on it, even though it was used as a retune over the top of another non standard tune? 2) if so, and I do return the car to standard tune via the xcal, will the current tune for the blower be lost? Cheers
