Sorry for the short story, I'm typing this up in a hurry before I sign into work. Last night, me and a buddy of mine were out cruising around in the TGP. We got stopped at a red light and and when it turned green, I hammered the gas. The car took off like a bat out of hell, but maybe halfway through the intersection, the car fell on its face like the wastegate just suddenly opened or something. There was a loud air rushing noise when the turbo spooled. We drove it to our destination thinking I popped a boot off one of the charge pipes, but the boots were intact and connected as they should be. All the vacuum lines look intact (aside from the ones under the plenum, I can't check those, but I'd imagine they're fine). We were stumped, so we drove home and figured we'd futz with it the next morning. On the way home, I got stuck at another light so I hammered the gas again just to see what would happen. The car shuddered slightly and then took off and hauled ass like normal. What the hell? Got on the highway and the car never pulled so good.

On the way back home, the car started the same strange air rushing noise and no power. Same thing on the way to work today. Also, is it normal for the Jeff M chip to intermittanty turn the cooling fans on when the key is off? I know my DHP in my Regal did this, but I don't know if Jeff did. There seems to be no rhyme or reason for when they turn on, they just sometimes do after key off. Sometimes they'll run for 5 seconds, sometimes they'll run for a minute or two. The cafr was previously throwing a code for the knock sensor which I'm going to fix tonight, but I don't feel that it's the source of my problems. What the fuck is wrong with this car?!  :icon_cry:

a knock code is really not good you should fix that first.  sounds like the car hit boost cut or something... what is fuel cutoff on jeffs chip 11.5 psi or something?  maybe boost solenoid going bad?

the fans comming on when the keys off is in the stock programming, that usually means you didnt wait long enough to turn the car off after hot rodding it. Didnt you read the sticker on the visor, lol.

I read the sticker! lol I always let it cool down for a minute or two before turning the car off.

Anyhow, update:

Replaced the knock sensor. Drove the car again and the problems were immediately there. Drove it back to the garage and opened the hood to look for any possible leaks. Again, there were none. I made a comment to Chris that the ECM/Chip could be bad so I smacked the shit out of the ECM with a screwdriver because I was pissed. Drove the car home and it ran much better. There was a slight stumble but it felt more like a bunk tank of gas. I was low on fuel anyway, so I put 13 gallons of fresh 93 in from BP. Car drove a little better on the way home. It's boosting now but it doesn't feel near to it's full potential. Fans at key off still happens at random. No real rhyme or reason.

I'm going over to swap the ECM with TGP 1.0 and we'll see where that gets us

Swapped the ECM, no go.
Swapped the boost control solenoid, no go.

Got rid of the shitty-ass upper charge pipe to TB coupler and everything is peachy! I don't know how we missed this the first go round.

I also changed the oil today and upon inspecting the underbody of the car I found that I had no right side subframe bushing retainer   :icon_eek:. It just wasn't there. At all. Put one from Chris' old subframe on and we're rockin'! Maybe THAT'S why I had no torque and the car handled for ass. I can't believe that passed three separate state inspections.
