I just wanted to share my first experience with tuning my own ralliart. I did some logging with PCMscan and just slightly tweaked my timing and boost target maps. I flashed the ecu with ECUflash and went for a test run. It was immediately obvious that there was a power increase as the car continued to pull as the rpm's increased rather than giving up. I am new to tuning and have no prior experience but have been doing ALOT of reading here and decided to try this myself. I think I'm hooked. Its fantastic watching the graphs change for the better after altering a few simple cells in the rom maps. If there are others out there tuning their own ralliarts it would be great to hear some of your experiences.
