This is hard to explain...When I am driving and in the boost, say 3rd gear at 4K RPM's, jump on the gas, the tach rises quickly WITHOUT the power. I guess it acts as if there may be a turbo hose leak somewhere. It seemed to begin after replacing the ignition module, though probably unrelated. Also, the gear doesn't matter.

Thanks for the help,

If the tach (and thus, the engine) accelerate but the car doesn't, it's your clutch.
