So after hooking up the wideband and setting up the LC-1 voltage output for the gauge (analog), I've been adding fuel all weekend and am now at about 14.6 A/F @ WOT after adding 10 with the tuner! Each time I add fuel I can feel more and more pull. I had to park her yesterday because of the rain and it was a bit scary, had to drive like I was in my wife's car! :D Both sides of the EGR are plugged and it's shut off @ WOT anyway. More fuel coming! Supposed to rain through Wednesday though. :( I can't believe the pull she's got though! It's feeling close to the 100 shot of N2O once she's over 2k!

Got the A/F to 13.8. Still wants fuel! Tested a measured 1/8. 8.80secs @ 93.88. Didn't hook...

Nice how many runs did you get? You need put that thing on the dyno.

93.88 in the 1/8th?

Most SC cars arent even that fast!

Yeah my 1/8th was 9.016 @ 81.32 so you must be on the juice?

Not written in stone! Could be off a bit, not much though. I need to get her dynoed. No juice, sure as hell feels like it though!

Wow sounds like its coming along great. Do you have the Pro Racer software? Re: adding fuel. How are you doing this?

Also if you are running the short runner lower (to add top end) why run with the PHP spacer which effectively makes the runners longer by adding volume (length)?

The php spacer adds more available plenum volume and doesn't truely add to runner length since runner length has more to do with velocity in low end torque. Adding fuel with my SCT3.

That explains it, there is so much you can add without a dyno tune. Unless your a dealer or have the hook up. If you know what I mean. If you had an xcal2 it would be a different story. Keep if up brotha. I want to see some good #'s.
