what would this do

It does exactly what it says it does. It will raise your fuel pressure as if it were at full throttle all the time. Check out herefor a good write-up on it on an mx-3

it works....but it's not gonna snap you into your seat or anything. it will be most noticable at take off, after that it's pretty much the same just the throttle is a bit more responsive when you give it. You'll burn a bit more gas, so as it says....it's best to use it when you feel the need for a wee extra. I use a golf tee to plug the hose from the FPR.
