So I guess we can say she is making some pretty good power!!
We are hoping with raising the fuel pressure up slightly we can help out the duty cycle these injectors are seeing but prob wont be the cure. Looks like I may be needing some bigger injectors or going meth...

You don't need bigger injectors as long as you can get the right pressure. It sounds like the fuel system is lacking more than the injectors. Your duty cycle may be a little high but it isn't worth going through the trouble of wiring in a box etc. I've done cars with 60s and gone well over 800 and i've seen 42's go over 1000 (i don't recomend the latter but it is done lol). **** there are three examples in the june issue of motor trend lol.

Hey I forgot to ask. What are you using as the fuel lines? If you are using the stock lines the bigger 8AN line will flow a whole lot more volume and speaks a ton for the fuel system. I can't remember what we talked about what you did in that department it could possible help you out though I had to lower my FP a lot for the same setup basicly I ran before went from 58-50 PSI and still had to pull 8-10% out of the fuel trims. Some of that was the meth injection though. I am sure you'll get it worked out.

I'm thinkin' I may work my way up to about 70psi base because of the amount of boost they're seeing (18lbs) which will take a few lbs away at WOT anyway...at least thats my understanding.
