Dennis-

The LH/EZK has no provision for boost that I'm aware of. If the OP is running stock fuel/ignition maps, then he's probably too advanced for boost and is most likely experiencing detonation. The EZK does, however have the ability to retard timing if it detects knock up to a maximum of 6 degrees (or is it 9?).

However with a sharktuner, you can adjust timing and get a map that is more inline with the needs of the engine.

What spark plugs are you running? It is recommended to run two ranges colder than stock on a supercharged engine.

Thank you for all the suggestions. I am guessing it has to do with the air fuel ratio 14.5/1 This going to be addressed at Auto Stop in Bozeman after the long weekend.

Dan,
I think my 928 has a Gt motor and trans in it engine code M28471 and trans. code 2J10547. I had it dynoed and sent the results to Murph, 322 hp 316 torque he said these #'s should be at least 50 to 75 hp more. What brand SC do you have?
