My 83 turbo seems to run rich. The new tip I put on the exhaust started getting soot deposits on it immediately. I replaced the cat with a straight pipe and the power increase was suprising, but my turbo is expiring and power has dropped off again. BTW when I replaced the 1.75 inch pipe someone put on my car, the power jumped for a day and dropped off again, humh. Other richness becomes evident when the boost gets up there, black smoke under hard acceleration and an occassional back-fire through the intake. Whats up with that?
Thanks Doug!
