Hey guys, I’m rather new to the forum and Subaru’s in general. I bought a 2011 WRX about 2 weeks ago with 62k miles. Runs strong, and the only thing off in my log that I see is overboost. To my knowledge the only mod to the car is the Cobb SF intake and I used my V2 AP to flash the LWG Stage 1+ SF intake 93 map. I believe target boost is right around 17.5psi and it spikes to 19+ in 3rd+4th WOT which from reading I’ve learned is a somewhat normal thing with this car. I’d like to fix the overboost and have it somewhat closer to the 17.5psi target. While the overboosting isn’t necessarily an issue if I lift when I see it happening, the issue is when I don’t have my AP hooked up and I approach WOT and I get fuel cut (assuming this is what happens if I don’t lift on overboost). It’s not a pleasant thing when it happens, and it’s only happened once because I’ve never pushed it, but I’d like to get to the bottom of this. 3 fixes I’ve seen (not saying they’re correct, just what I’ve seen) 1) put stock intake on 2) go EWG which I don’t want to and 3) get a protune. Option 1 of installing the stock intake seems like the most likely solution to me, if it is a solution.
In this log I downshifted from 4th to 3rd around the 15.4 second mark and pulled through 3rd, pulled through 4th, and a bit into 5th. I did NOT push it as far as to get fuel cut in this log. But I believe it does spike around 19psi.
Any help is appreciated. You guys are the most knowledgeable bunch out there!
