Running my fuel pressure at 44psi I think I figured out why I couldn't lean out the tuning with the MAFT. Last time I had the computer sent to Ed, I think he tuned for standard 42lb injectors. Since I am running SVO 42lb injectors, the car was consistently running rich at WOT because they were putting out more like 50+ pound injectors at 60psi.
Since SVO injectors are rated at 43psi, I decided to crank the pressure back to 44psi. Autotap'd on the road today through 1st, 2nd, and 3rd. O2s were reading a little rich, but not nearly as bad. From .910 to .925. I will try to lean things out now witht he MAFT and see what happens.
Can't wait until I can buy LS1 edit and get this thing really fine tuned. I think I can see 380rwhp on a 9:1 motor with good tuning.
