Stage 2 help
So i finally got to installing my downpipe, and now we have some issues. This was my first time doing anything major to any car. I have a '11 hatch with Cobb AP running stage 1 for about a month now without any problems. It took me almost all day to take the stock pipe off and put the new one on. Its a Cobb catted bellmouth. After I got the turbo shield back on her, I connected the AP and flashed to the stage 2 map, and then did the ecu reset on the AP. I then started her up, and it took a bit longer, which is pretty normal I hear. Anyways, I got really excited about the sound and all, but then that turned to horror when I went to check for any leaks.
I forgot to put the IC back on, so the engine ran for about 15-20 seconds in neutral without it. After I put the IC back on, I again reset the ecu and started her up again. After about 15 seconds or so, some light white smoke started coming out from underneath the turbo shield. It was gently rising, and not being forced out. The smoke had no real odor, all I could smell was just the normal engine bay odor. During the removal of the stock pipe I used quite a bit of PB blaster, so I was guessing it was just that being burned up, or maybe some oils or whatnot that may have been on the new DP??
The car sounded fine, and no CELs came up, so I decided to hook up the AP and drive it around the block. The car drove fine, but when I clicked on boost levels on the AP, all I could manage was between -10 and -3 psi. I only took her up to about 3.5K rpm, and kept it under 3K most of the ride. I can hear the turbo spooling up, and what I think is the BOV(ima noob, and this is my first turbo car). The car sounded fine, no strange noises that I could make out. I switched to the AFR sensor, and it was pretty much around 14.5, +/-.3 or so when I was on the gas, but when I let off the gas, the AFR jumps up to around 20. I'm guessing thats not normal? I didnt datalog anything, I just knew something was wrong so I headed back to the house ASAP.
So the question is, what could it be? I know it could be a leak somewhere, probs around the IC? I also saw posts concerning the white smoke with people saying it could be the rings, or some other nasty internal problems. How should I proceed? I dont know it this is related, but another thing I thought was strange was the AP flash to stage 1. I bought the AP at the dealership, and the "expert" put it in for me, and flashed/reset it to stage 1. What I didnt understand was that he messed around with some cables under the glovebox. It's a cable with a green connector, and he left it unhooked. What is that cable for? Should it be unhooked? Sorry for the longest post in the history of man, but I wanted to be thorough lol.
