I just installed some Pacesetter LTs, Deleted AIR and EGR. On the way home I noticed my car didnt want to rev up.. Seems like she wants to bog at anything over 3000 RPM and also Revs down slow. I dont think I have an exhaust leak... Dont hear or see anything. Car starts up fine and idles fine so im at a lose here.

 

maybe make sure that the egr blockoff plate on the back of the intake is sealed good, thats the only thing I can think of that is related to your mod. Other than that I dont know

 

when i installed my pacesetters the coating burned off and ruined the o2 sensors, replacing the sensors fixed a very similar problem
