If you're worried about fuel delivery, get 21#/hr injectors (IIRC, injectors are rated at pounds of fuel delivery per hour, @ 80% duty cycle, @ a specified pressure. The pressure can be corrected for mathematically. I don't recall the equation offhand, but it can be found easily and is fairly simple - try Marren Fuel Injection, I think it's there.
www.injector.com, I think. MSD may have it as well.)
The slight increase should allow the duty cycle of your injectors to adjust downward similarly (which helps the injectors and makes for more efficient fuel delivery,) and you can fine-tune fuel trim using an adjustable MAP sensor - which is cheaper to build and probably allows you more adjustability anyhow.
NB: It's useless to have the means to fine-tune fuel delivery without having the ability to monitor your exhaust! This means a "Wideband HEGO" (preferred) or an exhaust pyrometer (OK.) I believe Innovate Motorsports will have the better option of a Wideband HEGO, and this will allow you to see what effect your changes have. You'll probably need to weld another bung into your exhaust collector, but it's worth the trouble. Do that while you've got the exhaust out anyhow - any exhaust shop can do it for you, since HEGO sensors all use a standard thread (M18-1.5, they probably have a boxful of bungs and plugs. Get a plug when you get the bung welded in, and have the bung welded in just
after the OEM and slightly off-angled, you don't want it directly in line. It needs its own sample of exhaust gas.)
