BTW, my shop will hopefully be able to a custom dyno-tune before the summer's out. Some tuners from Phoenix were there with an 800+hp GT2. They got some bootleg software out of Germany and my tuner is trying to work a deal to bring it to Colorado. Looking at my AFR curves, all the tuners were guessing that there's 15 or so hp in just AFR and no telling what if we work with the VANOs and fuel mixes. We'll see, I hope.
