Whats the best fuel pressure? Ok, I'm running a stock LS1 in my '87 RX7. It does have a nice "cold air" setup, and dual 2.5 inch exhaust w/ x-over and Borla XR1's.
I've read several different settings in the books, but am curious what you guys suggest!
It's just not running as smooth as it can run. Feels like it stumbling under load (5th gear uphill).
Thanks!

Re: Whats the best fuel pressure? Stock ls1's have around 59psi at idle, and then when put under load the psi usually drops from 59 gradually to 53-54 by 6100rpms.
