Yeah, bead the pipes and put on T-Bolt clamps. I've had no problems with any of mine that were done that way. There is one coupler in my setup that is held on with regular worm clamps and no bead. That one has popped off once. So there you go, bead the pipes and use T-Bolts clamps
As for cutting the temp wire. I asked another more experienced guy and he says to disconnect all the O2 sensors instead of cutting the temp wire to force closed loop. Note: You must have a very fast and accurate Wideband O2 and EGT gauge if you're gonna do that! I think your best bet would be the Splitsec unit if you want to force closed loop. Either way though, these are all band-aid solutions. Eventually when you get around the 500-600HP+ range you're gonna need to go standalone or some system that has full control of the engine.

A popped out coupler is what i thought would be the culprit and my hunch was correct. You should definitely look into beading your pipes and getting t bolts as suggested by Mikal and Jeff.

Beading the pipes is going to make the biggest difference, T-bolt clams are not that big of a deal and are more likely to leak than a worm drive. Reason being is there is a section just under the bolt that has less pressure than the rest of the clamp. It can lead to leakage, worm clamps are better for someone in your situation(and cheaper ).

Hey, lexmada....I got a question for you. Does your turbo spin while the car is idling? Mine will only spin if I rev it up for a sec, but it slowly comes to a stop once the car settles back at idle speed of 650-700rpm or so. I guess it's because my turbo is so big lol. It's rated to put out 650-700hp lol I'll get there eventually

Not sure what could be the possible problem, but honestly ditch the SAFC and run an AEM Plug and Play unit. It is pretty much readily available. There is a shop who is claiming no check engine light either. Cost = $2k
