Is it really worth it, what improvement can be expected, talking about using it with the stock throttle body currently, wanted another, but not expecting to go all the way to a 75, seems too large. I think a 75 will require the fuel to be increased, not to mention my micro-tuner would not work with it, likely need a different burn. Looking for a power increase, maximize the use of the E-85 I've been running for over a year, hope for a MPG increase too.

Thinking of giving something like this a try too. &NR=1

i've heard that porting and polishing works ok. worth it if ya do it yourself...not sure if its worth it to send it in and pay for it.

I meant the elbow, I'd rather look into swapping in a 75mm TB to go with it.
