I've recently installed the stage 1+ APR program and new injectors on my 2005 A4. I also have a DV and intake and since this work has been done I feel like the car is driving funny in 5th and 6th gear. When I romp on the gas I feel like the engine makes an odd rumbling noise almost as if something is knocking around in engine ro turob. Has anyone had this happen or is this supposed to happen with the upgrades?
Also, is there anyway to test if there is back pressure after I let off the gas because I feel as though the turbo is spiking a lot differently when I let off the gas.
Thanks for the input guys.
