after logging about 10k miles on the Newell, I have this problem that I need to address. First of all, the engine seems low on power at times. I have changed the fuel and air filters, and have not seen any improvement. The symptoms are at times, the engine will not build boost over 8lbs. This is very problematic on hills. Any suggestions on what the cause could be?
Check for leaks around boots and on the pressure side of your turbo, several things can cause a lack of air. I know restrictive exhaust can cause this type of problem too. Low fuel pressure can cause the problem just like not enough air and too much fuel. But you would have excessive smoke. How many miles on this engine? How long since a full service?
