Answered my own question, did the install, not as bad as I thought. Only intake tube, air box lid, battery and box had to come out. Unbolted ECU from battery box so no de-mate.
Verdict: about as expected, biggest difference the occasional hard shift into first at a stop where you have to shift into 2nd then first is gone. Hard detent through neutral when shifting is lessened. Only downside is a metallic "clicky" feel to shifter now, somebody described it as "feels like a bolt action rifle." Makes me think hard urethane replacement for stock bushings rather than solid might have been the better idea. Would I go back to stock though? No.
