TexasCamaro, I think you can be happy with those numbers. Yeah they are not the best "for show" numbers because they seem low, but its obvious it is a low reading dyno. On a different dynojet you should be in the 270s or higher forsure with those mods.
35 - 40 HP gain with those mods would have been nicer, but 30 is still a good gain. I'd suspect your gain in the mid to mid-upper RPM range is higher than that.
5th gen IS SOLD! 6th gen built 10/14!!! Can't wait!!
