Simple (hopefully) Problem PO102
Yesterday I was driving through town, recognize a HUGE power loss, 3-4PSI max and RPM's creeped up. Didn't throw a code at first, went home, checked charge piping & MAF sensor. Started it up once it cooled off outside, runs fine but threw PO102. Occasionally I will feel power surges while driving but nothing great.
What should I check next? I didn't clean the MAF but theres no vaccuum leaks in the intake.
Hahn CAI, Hahn Catback, Turbo XS charge pipe & Tubo XS catted downpipe. HPtuners

I just went through the same issue. You have a massive boost leak, you won't be able to see it visually, you will have to perform a boost leak test to know where it is for sure. Most likely your inter cooler is cracked and will need to be replaced. My intercooler looked fine but during my boost leak test air was pouring out of a small crack in the end tank.

Thats exactly what i was hoping it couldnt be lol
but "P0102 Mass Air Flow (MAF) Sensor Circuit Low Frequency -PCM" how does a leak cause that?
50%ish I'm driving it runs perfect though, id think a boost leak would be pretty consistent
I'll check maf wires with a volt meter then throw a boost leak kit together. too bad i cant use the pressure test kit I already have thats for swimming pool plumbing!

Well I did a boost leak test and it was whistling by the hotside, took the front fender off and repeated, it was just the clamp(WHEW!).
Took the ECU connections off for a few minutes, started it up...no CEL. Restarted it about 5 minutes later and CEL is back...any ideas?
