I have so many questions. I'm considering the stage 4 kit
How does the hydraulic clutch handle the power upgrade
Is it worth the $5000 to do it
And are you getting what they say you get ( HP an TQ ) or can you get more
Are you doing this to keep warranty, or doing it to have the best running motor?
I would check on a turbo.
Welcome to the site. Visit the dyno section for some examples. You'll also see the Milwaukee Eight section has a couple of sections with some testing by highly qualified people sharing their findings. Between those 2 sections you should be more informed based on real info instead of "If I were you I would ......" type of answers.
I would do it reallY for both reasons. I think it makes the most sense.
Kind of like guy at dyno said , when you make power you chase the weak link, you may have to put in a pressure plate with more tension to grab them ponies
