I neglected to mention that part of it. One way that you can actually get use out of a fuel pressure change is to go to a dyno or track where you can do a lot of runs. Reset your computer and keep tweaking the pressure until you get the results you want. When you drive it around town, the EEC will adjust, but the next time you go to the track all you have to do is reset the computer again.

Running a richer throughout the powerband will definitely help you run better. It should get your more than a tenth, too. When I bumped my fuel pressure up to 45, I could definitely feel the difference. After a while, though, it settled back to normal. I wasn't starving for fuel, anymore, though.

I want to get a speedbrain or an SVO extender when I can afford one.
