On my baseline the car only did 306 rwhp. The tuner told me it was running very rich. The a/f ratio was in the high 9's at wot, probably do to my descreened maf. After about 7 pulls I walked away with 369rwhp and 381tq! The a/f ratio was around 12.7 on the last pull. The #'s seem high but even if the dyno is off by some amount it still went from 306 to 369. He said it was very strong for an almost stock ls1. Only mods are CAI, gutted MAF, 160 thermostat, no cats, x-pipe, no mufflers. I don't even have longtubes yet.

i would say that pretty close, your trapping at 113. nice!

I would think those numbers are high myself. However, turning a 12.6 on a 1.9 sixty foot is the real deal. Congratts...you have a screaming motor. Just wait till you add Long tube headers !!

That seems a little high I trapped 119 with 375rwhp (or maybe mine are a little low), but either way you aren't doing bad...looks like you might have the driver mod installed to hit a 12.6 with that number.

With my first car I had a set of lg pro long tubes, shitty homemade stock modified h-pipe that was really home made,..looked good, sealed for ****. Point is, through stock mufflers, vararam, LS6 intake,...tuned on the dyno it made 355rwhp like that. 6 speed
