you know probably not many, Had the turbo on the last one, sure it was a ton of fun and all but may just leave this one fairly stock pump gas pull and go warrenty deal, my local dealers great and it has there own 3 year powertrain warrenty so IDK, maybe slp stage 4 if that. Damn sleds are getting so good you really don't need to do much at all.
Solid swap! You are correct about the technology, pretty amazing how far sleds have come even over the last 5-10 years nevermind farther back than that.
