Alright, I'm in need of help. I have the dreaded 30ff code now. Everything was fine and I had to take the car back to stock for PA emissions. Cats back on, unwire the ethanol on the dme and replace the 3.5 bar map sensor with the stock. Same thing I do every year.
Only difference from this year to other years is that I'm a beta tester for MHD and when the anti lag came out, I couldn't get past 9 lbs of boost after that update. I sent logs into MHD and ended up deleting my MHD and backloaded MHD on my phone to upload a new version. Worked great. Fast forward to today and I go back to a stock tune with MHD still applied. No boost. Tried a Stage 1 tune. No boost. So no boost and I've only made mechanical changes of swapping down pipes and cats. Electical changes are disconnecting the Motive FlexFuel and the 3.5 bar senson on the charge pipe.
I have a boost leak kit and pushed that until the oil cap was leaking air. No leaks. Not convinced, I bought a smoker and smoked the system. No leaks. I checked the inlets, all of the vacuum hoses, which were all replaced about 6 months ago, the boost solenoids are only 1 year old. I was convinced it was something with the tune. So I switched back to my custom tune yesterday with my cats still on and suddenly I could get up to 7 lbs of boost. Today I put the down pipes back on and again I have zero boost and the 30ff code if I get on it hard.
I'm not normally this dumbfounded, but I'm getting my ass kicked with this one.
Any thoughts?
Also, I've posted this exact text on a couple facebook pages, so if you see, It's just me being desperate...
