OK HERES THE SITUATION, i just got my FD back from the shop. it wasnt boosting properly. now its boosting and boosting well. heres my setup so it can be diagnosed by you local pros, got a nice street port, greddy 3 row smic, greddy pulleys, apexi intake, hks 3 inch downpipe, 3 inch midpipe, 3 inch catback blitz exhaust, apexi avc r is running about 10 pounds or so maybe 11. Here is the situation thats concerning me. Im running full throttle through 1st and 2nd fine, once i get to 3rd gear at about 4800-5000 rpm is lets out this loud burp sound, nice like a backfire, but a burp, and the boost drops and the car virtually stops accelerating, my air to fuel gauge says im running lil bit rich. Does anyone have any ideas what this could be??? its bothering me, im getting ready to put in my microtech and i want to know if i should jus tog ahea dand put it in and tune it and be done with the problem or fix it first.

if your running stock ECU with those mods, your probably leaning out. That air fuel guage is worth nothing when your trying to tell your airfuel ratio unless you have a wideband o2 sensor setup in your car and the guage is reading that

so i take it me replacing the stock ecu with my microtech will help the issue at hand, and i need a different o2 sensor, so i need to be careful driving it so it doesnt ignite lol, any other suggestions? get new fuel pump in process, new injectors, new fuel rails, microtech, and map it out, should be sitting pretty.

Yep, throw you're Microtech in it and tune it. Should solve the problem.
