Bought the car recently and every since I've had it it cuts out some under boost figured it probably needed plugs but it recently poped up the p0244 code and when boosting regardless of gear it cuts out some mostly in higher gears. When it builds boost you can watch the gauge run up to 15psi then immediately back to 7.5 without me moving my foot from the pedal. The car has a perrin up pipe /intake intercooler piping , cobb turbo back, aftermarket intercooler, (supposodly sti pink injectors) and cobb tuned. I know basically nothing about these cobb tuners and would really like to know What I should do to fix the "boost surging" like it does and I guess the boost creep is what makes the p0244 code. Any help is apreciated. Thanks.
