I'm putting some serious thought into purchasing a 2021. Like most of us older folks a Manual transmission is a must. With more options this year I'm balancing the price difference between an SL with 178 HP and an R with 203 HP. Big price difference. Also thoughts that the ProStar Stage 1 tune kit is something I can add to the SL in the future if it is compatible with the 2021 SL? I checked on line and it states the stage 1 tune kit is not compatible with the 2021 SL, I suspect its only because it's not updated yet? At this point the only experience I have is the stock GM 2.4 Ecotec 173 HP and a lower RPM range for that engine. I'm OK with the performance but just want a little bit more. In short I'd be happy with modest gain in the fun level that a small HP gain along with a higher RPM range may be all I'm looking for?
Can anyone out there that has driven a Slingshot with a GM 2.4 VS the Polaris 2.0 prostar 178 HP engine tell that there is a noticeable difference in the fun to drive area. I'm not worried about the torque output.
My thought is that driving the hills and curves and being able to down shift gives better fun experience.
