Long story short, bought a Cobb Accessport last year and flashed one of their OTS stage 1 maps to my bone stock 2006 WRX TR and from that moment on it has been one long headache.
I have flashed the stock map back on until this is figured out of course.
Basically under hard throttle at right about 4000 RPM or so it feels like the car hits redline or fuel cut, I can keep the pedal floored and the RPMs will rise very very slowly up to about 5k and it won't go any higher.
Fuel pressure is getting up to 70+ P.S.I. when the problem occurs too.
If there is a stage 1 map on the car the "cut" happens around 3300 RPM instead of 4k.
The car has been to multiple shops including 2 months at the dealer and of course they all "know" what the problem is but it never turns out to be right.
I can datalog anything you want with RomRaider if it'll help any too...
So many things have been replaced...
Boost Control Solenoid
Fuel Pressure Regulator
Bulkhead Wire Harness (It had some spliced wires in it and was changed to eliminate suspicion.)
Downpipe and Midpipe Cats
Front AND Rear O2 Sensors
New ECM was tried by Subaru but didn't help any so they put the original one back in.
Turbo was replaced under warranty 2 years ago.
I'm just looking for any fresh ideas on this, it has taken all of my money and I don't know what else to do.
Thanks for ANY help you kind folks can give.
