    How do i make my car run richer?? 2010 wrx w/ AP

    hi, i have a 2010 wrx with an up pipe, invidia divorced catless downpipe, and invidia q300 catback. I use the accessport stage 2 off the shelf map and it seems to be running a bit lean. How do i set up a richer tune?? thanks

    Have a professional do it. Respectfully, this question means you shouldn't be altering the ECU parameters.

    Unfortunately this is an example of garbage internet rumors.

    Someone probably told the OP at one point that the "Stock tune is lean."

    OP, what credible proof do you have that the car is running lean into boost? I have datalogged Cobb's OTS maps with a WBO2 sensor, and for the most part the maps are running very high BSFC i.e. very rich in high load cells.

    would a leak in the up pipe cause it to run lean?? my mechanic is the one who told me and he had said the bolts backed themselves out and he had to retighten them awhile ago.... maybe theyre starting to back out again..

    It could run lean, but only in closed loop operation. You have not answered my question.

    A tune is the solution...but answer Zax's questions.

    You can't just assume a car is running lean without having proof from datalogging, period. Run some logs, get a WBO2 and get concrete evidence.
