for whatever reason my car sems like it makes more power at almost full throttle than wide open. its not quite bogging but is holding back a bit. plugs and wires are fresh/gapped properly. dist cap/rotor are new. this made no difference for me. to dpfi cars have a tps like the a6's do? could the 02 sensor cause this? car isnt showing any codes.

 

Check the timing? Also did you switch the wires for the tps on a dpfi to mpfi?

 

didnt check timing yet. the car is bone stock so i wouldnt need to switch wires. but i assume this means the dpfi cars have a tps?

 

Install a Vaccuum gauge on the engine and check you needle reading. If the needle gradually drops to zero you have an exhaust restriction. Give a visual inspection of your exhaust sytem.
