1990 E7 400 mechanical / 1988 E6 300 mechanical

Recommended Posts

Does anyone know what kind of manifold pressure and fuel pressure I should be getting out of these engines if they are running good?

Without changing the turbo, etc, what is the best way to get max fuel / max power out of these engines.


Regards, Bob..........

90 e7 400 = fuel spec 21-37 boost 20-28 88 e6300 fuel 22-38 boost 15-23 best this to do is make sure you keep a good tuneup on the engine no boost leaks clean fuel , can bump timing up a coulpe degrees help a little or can have pump recalibrated at pump shop new set of spark plugs if you are still running orginals .
