so if i just remove the exhuast after the turbo and have the 3 inch downpipe open then the p0300 should go away? I took off my recirc pipe. it connects the 2 wastegates to my Fast intentions exhaust. theres basicly a huge hole in the exhaust from where the 2 wastegates dump into the exhaust.

also i wasn't aware of the idle hunt, this is some real good information. I thought my timing was off because it kept moving up and down. My E85 gauge/flex fuel is tied into my ECU, i have it pinned in so my ECU does control my tune through the ethanol content coming in.

Research the code on here. You are not even close.

Sorry man im not understanding you. I tried researching the code, when you say exhaust leak, i have a B/P single turbo kit, the turbo attaches to the manifold and a 3 inch pipe comes off the turbo. There is no other exhaust that it could leak from once i take off the rest of the exhaust. How would it be an exhaust leak?

Ill double check where the headers mount to the motor and the T flange on the turbo when i get home, im pretty sure they’re gucci. New header gaskets as well, but maybe i forgot something!

Ill keep you updated (:
