Back then I ran a gt2871-2
After riding a sidekick, Boonedocker should be ashamed. Rather ride a light weight stocker.
But I'm looking at a boost it, I think Racin station has some. So far it's the only kit that has what I think it will take to make it worth it. Hopefully I'll know soon
I'm really happy with the boost-it turbo with a gtx wheel on my 2016 M8 LTD 162.
They suggest mixing 50/50 premium/race fuel at 6-8 lbs.
Maybe you'll find out you can run less octane.
