Hey guys. I have an 02 wrx I recently purchased. Already have a newer trans in there because I bought it with bad trans. Anyways I also installed a cheap boost guage. The car is lagging on acceleration and even driving a bit rough. Im not sure what the problem is but here are the issues at hand:
Studders to accelerate. Very choppy
Boost guage flutters wild. Then sits at 5psi then flutters again.
Front upstream o2 sensor heat code is going off as soon as car is turned on even after clearing codes.
Any help is GREATLY APPRECIATED. you guys are my only hope. My local mechanics all suck.. Pretty sure im the only one within 50 miles who owns a turbo and a bov. Lol
