If the former, it's almost definitely that the OEM tune just isn't as responsive as it could be (there's a whole thread on this with tuning code that can be cut and pasted into uprev).

If the latter, it could be any number of things including vac leaks, wonky sensor, etc. Even clogged air filters could cause that.

Tell us more about your set up. Is it all stock? Do you have any datalogging capability?

Yeah it feels like clogged air filters to me. It's like it's starving for air till about 3500 rpm then it will surge forward and is fine at high rpms. It's mainly taking off and when I get on it at lower rpms it's like I said starved for air. And no data logging or anything like that. It's got full exhaust. FI test pipes aam mid pipe and shirt tails. That's all that's done as far as power mods.
