Default Headers / intake power band

I reposted this from the performance results section. That area has no activity lately.

I have a 2003 base that i just had dyno tuned with TSP catless longtubes, corsa indys, and a vararam with the powerduct. It made 335 whp and 355 wtq. Those are the numbers it should have made, but it actually feels lazy / less punchy to drive. It definitely feels like the power band shifted to the right. It pulls a little harder in 3rd and 4th but feels like it lossed some torque in 1 and 2. It runs great though, im just unpleasantly surprised by the feel. I want to get it to the drag strip to really see if its pulling the way it should.

Did anyone else experience this with these mods?

auto (if so what gear ratio) or manual?... it's also possible the low end was softened up in the tune

Maybe tuner put in a safe tune where it's pulling timing with false positives Knock.
