Look up maxbore.com and a salvaged throttle body for 300 or less you can get your self a larger bore TB. The Dinan larget TB recived mixed reviews, but it seems that for what you described this would be the easiest option.




There is no Alpha N tune, I asked Evolve. They dont have any desire to try at this time. I also have a spare manifold.
oh ok i thought he mentioned that he was on stock internals and made 300whp.

I understand about the Alpha N tune not being an "off the shelf" thing. I was just wondering if all it took was custom tuning. Meaning is there a tuner that can do it?

what are your guys' questions? In my college when we built a racecar we tuned our engines with something like an alpha N tune so i have a little bit of an idea. the thing is that this would be about as difficult as tuning our ecu for a supercharger, and since that was already hard to do, I fear this is going to have the same restriction that tuning valvetronic with alpha n is going to be very complicated.
