I lived the turbo life for 3 years. The most important thing is the tune. Make sure the tuner sets it up for you. Not just WOT. That happened to me from Williford racing in NC. I told him atleast 8 times it was a street bike. He tuned it for WOT only. My AF at part throttle 65mph cruise was 16.8-1 when I had it checked by another shop. When we richened it up I gained 27hp! But by that time the damaged was done mostly with my ROSS pistons had started to come apart.
