Anti-Venom SS

iTrader: (3)

Hello, I have a BIG problem. I have an A4 SS camaro with an MS4 and heads. I just put some 42# injectors on it and had it mail-order tuned by TSP. It idle's fine and when at cruising speed, it does fine. But when I give it throttle the car goes into limp mode, and, for lack of better words, bogs out. I decided to see what happened when I kept WOT and I hammered it to 5k rpm and it bogged the entire time, I held it steady at 5k and you could FEEL the car get out of limp and run smooth (once again holding the throttle steady). HELP!!! I was hoping to run my car this weekend, but not like this ha ha. I replaced both O2 sensors and am getting the codes P1154 and P0153. Would this cause the problem?
