OK I installed my SRT intake with race-ecu about 6 weeks ago, since then put about 2k miles on it. When I first installed the intake the car felt much stronger on the top end, and about the same on the low end. However, I am driving my car around now and I can swear by my butt dyno the car has gotten considerably slower in the past 2 weeks. The top end just doesnt have any "oomph" like it did before. The power curve kind of flattens out more it seems after 4k rpm. I can't put my finger on it, and I don't know what to do. No CEL, so I'm good there. I reset the ECU, but it didnt make a difference. Then I cleaned the MAF, still no go. I'm positive I felt a surge of power after 4k rpm when I first intalled the intake. Maybe its the soldering of the race-ecu? I installed it myself, and it was my frist time soldering anything, so maybe the connections on the wires are poor? Would that affect performance? Wouldn't I get a CEL if that was the case? I will glady give +rep to anyone who helps. Thanks guys.
