here's my situation. i have a d16z6 with a drag turbo @ 5lbs with a 12:1 fmu, inline pump, and msd ignition. well my car was running alright till i installed the inline fuel pump, thats when my car ran like crap. it sputters like crazy and does not feel the same at all. some of my friends said i am running rich and that is what is causing my sputtering since i changed my plugs, wires, and shot timing. we also did a compression test and it was all good across. it sputters the most at 3k to 4k in WOT and 1/4 throttle. it also cannot hold a good idle. also when it sputters my exhaust makes a weird bogging noise
