Lgs with tune

Thanks to Phil and the crew at Dynotech Engineering for the great tune. I installed the LGs no cats and they got 30HP out of the PCM calibration, 384HP/ 375torque

You gained 30 hp by dyno tuning or by adding LG headers and then dyno tuning?

Sounds like the results are based on LG headers and dyno-tune. Those are the results (actually closer to 40) I achieved after installing LG headers w/ cats and dyno.

That's good. There's more to be had, but DTE likely has you conservatively tuned, which is safe. The last completely stock ZO6's that we did LG headers only on I got 406/393 at the wheels (51rwhp gain) from an 03 ZO6 without the cats, and I got 390/383 to the wheels (44rwhp gain) on an 02 ZO6 with the high flow cats on. Other than a cold air intake both these cars were completely stock. Mind you, I tune on the agressive side, which explains these numbers and big drag strip gains from these cars. They're tuned on the edge. But here in Oregon we rarely see very extreme temps or other conditions that would be considered harsh environments, so I tune more agressive.

Still, good numbers!! LG headers rock. That's all I endorse, really.

They both took the time and made the effort to have their cars tuned and got good results. The one is running without cats.

Phil did tell me that he tuned it on the safe side. The car has lgs, and a blackwing. I'm happy with the the tune. My next upgrade will be hardened output shaft, cam and heads.

Even with some false-knock readings in the higher RPMs, I hit 335rwhp/356rwhp with a blackwing and LGs WITHOUT a tune. I have a tuning appointment next week and I can't wait to see my final numbers!
