Ya, agree with most of what's been said here. First, been through the ignition system in it's entirety and it is solid. What I know for sure is I get about 5 runs on it and the performance drops off ( engine miss ). Runs good when it's hittin on all 8 with speeds in the 129 MPH range, so the A/F can't be too far off at WOT. Yes, I gotta idle to staging and back to my pit area after my run. No boost, no miss. I can clean a set of plugs and make them work good again. I don't run an inner cooler. I do run a alcohol / water injection system. Run a mix - about 35% alcohol - probably do screwy things to a W/B 02 reading? Think I will try to drop some jet sizes and maybe put in a smaller water injection jet to see if that will help. My system is adjustable. I have it set for full spray pressure at 15 lbs of boost and over. Could try slowing it down? Also going to try a 1 step hotter plug.
