Back in May 2009, I had purchased a 2002 Subaru Impreza WRX wagon 5MT from a Mazda dealer (Autex) in Keene, NH. Being a NH sale, there was no warranty. I figured I could take care of any little rattle or anything that bugged me when I got it home. Well, little to my surprise, within 1 mile of leaving the lot I got a CEL :eek: I should have just turned around and taken my check back.
Beside having to replace the clutch, a downpipe, and a bunch of exhaust gaskets, the biggest headache was the CEL P0171 that I got from the dealer. The code is for an air leak; big help. I was also getting crap for boost; a combo of boost creep and boost crash. Had no idea what was going on.
In comes Bren Tuning. I posted my woes on Nasioc and he offered his services to help me get my WRX back up to speed. The Subaru specialist in Fitchburg couldn't figure out what was causing the CEL or the boost issues. Bren hooked up his software, read what was going on in the ECU and noticed my airflow #s were completely out of whack, even at idle. So he popped my hood, popped the hood in his Forester XT, and we switched MAF sensors. Instant cure to the CEL. Passed inspection and couldn't be happier.
Lastly was my crap boost issue. Looking at my boost lines, he noticed something was awry with what I had there. He grabbed his Forge MBC from his Forester, put it in place of my stock BCS, and took it for a spin. The boost then hit 15psi and stayed there. Nice smooth boost from start to finish. After a horrible long month of trying to get this going, Bren got me back up to speed in a week and gave me a tune that gave me a great daily driver at 23mpg.
I trusted Bren so much I just bought that Forester XT that he's custom tuned for me and my wife's use. It's an ecofriendly tune with a 3" catless downpipe that still can get front wheel spin on the automatic transmission.
So big thumbs up for Bren at BrenTuning. He seems to have that gift to be able to get his head into the ECU and get things running properly, and quickly.
