Following the instructions from ADC I crushed closed the end of the EGR tube that previously ran to the rear manifold. They say the EGR system is not used on a turboed contour. Doing this leaves the two tubes that lead to the differential pressure feedback sensor just hanging there. What should be done with these guys? Are they a vaccum source

On my returnless setup, there is probably less chance of heaving one cylinder leaner than another due to a dead head setup in the fuel rail, but for return-style rails, I bet money that the last injector before the pressure reg is a smidge leaner than the first injector on the rail - this is because unless the FPR clamps shut under boost (thus creating a

I have to reiterate the point that our engines run leaner than engines of the old days. The combustion temps are higher yet they still resist detonation and pinging better.
I have always run much higher EGT temps. I always made my best power when my car was NA with 13.2:1 A/F at WOT without any worries of pinging.
With the turbo this engine
