oh, that "ratio".

forgive me, its been a while since my engine theory classes.

either way, with 11.57:1 (not 11:57:1) static comp, its pretty high for forced induction, BUT it doesnt mean it cant be done. it just means your tune has less room for error. and we're not just talking about air/fuel ratios. part throttle, on/off boost transitions, ignition retard etc etc all must be spot on.

i'd recommend getting tuned on a dyno AND on the road. preferrably a road with lots of hills.
