415 rwhp aorund 400 tq a few questions why didnt you get a pulley and why the 90/90 combo are you planning to go bigger ci

SideStep

Good tuning and mild hand porting have shown 20+ rwhp lately from FAST 90/90 setups. The advantages are incremental and linear; it magnifies your current modifications basically. I am waiting for tax returns to do mine....

sorry, forgot to mention that it will have a pulley.
and the fast actually gains even on stock cubes...
and it will have a VERY good tune...
the cam on a 106icl makes 400/400 on stock heads full bolt ons btw.
