I know you can run an aftermarket UP with stage 2 (and you must have a DP too). Check the map notes (on Cobb's site) for stage 1 too though. An UP may be allowable with stage 1 as well (no other mods).

I plan on putting the one in the headers for sure for the gauge, that is why I will buy a new probe. I checked the notes on the stage 1 for my car and it says nothing about being able to run an UP or anything that is not factory. I finally found that last piece to the intake puzzle and put back on the stock intake and did an ECU reset like you said at lunch today. I took a really long lunch and put 20+ miles on it after the reset, and the car is still very inconsistent. It got a little better if at all. I had my friend take a couple of videos on his phone while I was accelerating to catch the inconsistency. The first video was in 2nd gear starting at about 3000 RPM on the tach. I was literally standing on the gas pedal and the tach was moving slower than just about any car I've seen. I would have gotten smoked by a 2.5 RS if he had started at the same point as me. It was real bad. The second video was from 1st gear through 3rd gear, and it was running like it did when it was new, great. Not to mention these videos were about 1-2 minutes apart from each other on the same road. I will definately stay out of the boost, I just had to see if taking off the intake helped at all. Not much if at all. It still stutters and surges really bad and I'm not sure what to do. I even had my friend that knows Subaru's really well and owns a WRX also to see if he could figure anything out and to show him that I wasn't crazy that my boost comes and goes as it pleases, and stutters when it does want to come out and play. He didn't know what to do at this point either. I don't know what to do at this point! I've been modding N/A cars since I started driving so I know what I'm doing for the most part, but this is my first turbo car. CEL did not come back on either!
