Re: car wont boost over 4 pounds
the turbo also leaks a little oil could thta be a problem?
we put in a dms, resistor box, and an ecu that was tuned on a t25 with dsms on single v, so kinda similar, but still no luck? |

His turbo flange gasket broke in 4 parts, creating a massive exhaust leak. You *will* come to find a leak in your pipes or somewhere in the exhaust pre-turbo. It could be a warped flange, ripped coupler, bad gasket, crack, or even a bad WG arm that has left the WG flapper opened. |
