If it's sluggish, maybe you're running too rich. Check your O2's for fouling or maybe you need a dynotune. I'm not sure how well a M6 PCM program does with a TH400. My throttle response improved tremendously after the A/F ratio was flatlined at ~12.5.

When I did mine(m6 to th400) it ran like **** and was really rich. Tuned it and now it hauls ***. I don't know why it did that either.

is the tranny kicking down (if your running an auto valvebody) or are you running a manual vb? if your still running an auto valvebody youll need to hook up a kickdown switch to let the tranny know your on the gas..just a thought....
