i dynoed 286.4 with 318.3 ft/lbs and that was lean too (13.9 a/f) with my mods and i've ran dead even with every stock LS1 WS6 i've ran on the street (from a roll) and even an 04 GTO (he might have been creeping away from me) and was ahead of every WS6 at the end of the race from a dig (couldnt pull me in). i believe the WS6 runs a low 13 when stock (maybe a high 12.9X). you should be running a solid mid 13 with that stuff. the misfire is probably killing you. i had a misfire at my topend (above 4K RPM) and i thought i needed a tune up/new opti. i actually ran my friends stock probe (just for kicks) and barely pulled on it. after calculating the cost plus the time and effort it takes to do plugs, wires and opti on an LT1 i decided to look further. i discovered that one of my wires had rotted and torn at the opti and was not even plugged in, it could still arch but under heavy loads would arch elsewhere too. turns out is wasnt the only wire that was rotting away. i replaced what needed to be and went on my way and it now runs great. replacing the opti should be a last resort. look around at your wires and if you decide to do your plugs and wires set aside an afternoon. especially if your not rerouting the wires. thats just my .02.

No I have not, adjustable fuel pressure regulator is now in and I pluged in the booster harness for the racetronix. I have also since lost 10 pounds lol. I also did not have time to lube the rear suspension parts that I have (have not since last year) so I am sure that hurt me a tad also.

I also need some rear pro stars before I can go back. That and I have been very busy these days so I doubt it will be back to the track this year.
