has any body tryed the POWRPRO Fi2000 yet. I like the idea of no more Dyno tune very time I change Pipes or any engin mods, or Is it only a piggy back system like Power commander ?

 

I have the powervision. Can retune anytime you want. Carry up to 6 maps at a time. Can alwys get new maps or recalculate the tune you are running. No dyno needed.
