Well 1st off I found out this whole time my T-rex wasn't working, the fuse holder was bad, so we replaced it. Then at 5000rpm, 10psi was blowing my spark out, so I'll be throwing on a 6A or crane. We tuned it to 5000, and it put down 389rwhp and 403 ftlbs. With 1250 more rpm, and some more ignition, I should hit my 400 mark. Air/fuel was set at 11.7-1, with 17 degrees total timing.
