You could also try a TB alignment and see if that helps with the missing. Personally I'd put my money on the ignition control module, i thought the cel ALWAYS flashed for misfires?

I think if the engine experiences more than a temporary misfire, the cel stays on. My engine misfired a bunch of times a while back and that's what happened to me.

it could also be the tune, he has not mention who tuned the thing, if it is even tuned for the 28rs.

Yeah, each new turbo setup needs a good tune by someone who knows what their doing. Backfires, misfires, running too lean or too rich are common results from a bad tune.
