The GT11 Cam is more of a low end/midrange Cam.So your not going to see huge peak #'s but a strong midrange which is what you want in a 4k lb car.

cats, resonators, and stock mufflers restricting what gains you would of had with the headers. Go with magnaflow 3" system and see those numbers back up were you wanted them.

Your numbers are where they should be. Your stock 385 seem a little high but I do not know where or how car was dynoed as long as you use the same dyno for your comparisons. I am using the LPE GT-11 cam in my Trailblazer SS and like it so much I am planing to use it in my SS Camaro as well. Do you have Hi-Flo CATS or what? A car here in my area has a slightly wilder cam and got to 440 rwhp, base pull of 370rwhp. Then he added ported heads and went close to 470 rwhp. Similar mods to yours. He has no CATS. Good Luck

I did a cam and headers and was at 443. I think your numbers are great to be honest.
I added ported heads and went up to 471. Bryan |

That is a really small cam, you gain 50 more rwhp from a bogegr cam if that is what you are looking for. Also, is your tuner over there familiar with how much spark advance you can run on the LS3/L92 heads with various camshaft profiles? Aside from those things, I think what you are making is pretty good power for the mods you have, if you want more get a bigger cam, or do some head work, etc.
