i keep seeing these on ebay. dyna fs? ricks hotshot? procom? are these worth the money? engine is 84mm bore,wiseco10.25-1. completely rebuilt topend and bottom end with wiseco crank. would this money be better spent on valvesprings and cam? head is ported with new valves and all new stuff(couldnt afford race cam at the time of build) runs great just looking for the advertised 3-4 horse increase that these boxes supposedly add. anyone actually feel a difference with the non-programmable boxes?
