Headers / intake power band
Hi all.
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?

I think im gonna ditch this tune and take it to ECS in Jersey. I dont think my tuner adjusted all of the right things. Not only that, he refuses to offer any road tuning which is most important for a street car. ECS says they do a combo of both street and dyno.

The entire rpm band feels lazy to me. I have to really beat on it to get it to move. 1st and 2nd are absolutely lathargic with 3 and 4 picking up a little but there is no explosive acceleration at all.
