My car hesitates and gts around 10 miles per galon on 93 Octane. Also the car wont start at all on a N332 ECU only start on a N326 ECU. Its a Turbo II but cant get it to run on the turbo ECU at all. And when i try to bosot the car or step on the gas the car hesitates a lot and only hits about 5psi of boost. What could be wrong with this? The wastegate opens and sound really loud for a internal and the exhaust fumes smell in the car
