Arizona Speed 500 EFI Mono Throttle Valve?
A simple wish from all of us motorheads to get more HP for less. ASM is advertising a 500 EFI Mono blade throttle valve that will flow 1300 CFM like the HP525.
With the new throttle body and recalibration of the ECU they are claiming a 25+m HP gain.. At $495 per motor it seems like a cheaper way to upgrade closer to a HP525.
Would this make much of a difference? Has anyone tried this up grade?
Has anyone used any products from Arizona Speed and Marine?

i have delt with them. they are pretty good. their stuff works. the throttle body is definitely an improvement, besides the throttle plate you may need to address your fuel pressure regulator.

I did this conversion and seen a little bit of speed improvment. More so the transom was cleaner. Mid range pulled better.
