I think there is. I am short shifting it at 6500, the timing is at 24 degrees, and the target AFR is 11.5 to 1. Next week I am going back to the dyno to lean out the tune up and find the optimal timing as well as see if it'll continue to make power up to 7500 rpm. I still also can leave on much higher boost. The suspension isn't tuned all the way but its pretty close. So there is still a lot of R&D to do. This is so much fun. I am also planning on taking my freshly dyno'd set up to Irwindale the following Thursday May 2.
