aftermarket efi controllers

[pj4]

i have an 07 can-am 800 efi.saw some aftermarket injection curve controllers. any one have any experience with these units? there is many different brands and type of units. just looking to up the low end power alittle for playing around. tried 30" mudlite xxl tires and lost too much on the low end. by the way, the 30" tires fit with no mods required. going to put a spring in the clutch to help raise the engagement rpm. be fun to crank up the power.

you should get the bottom end back from doing the clutch kit, if its done right. Otherwise the efi box should help

[Hafnutz]

I would start off with a good clutch kit and go from there. Your problem is more clutch related than fuel.

Paul and Hafnutz are correct. The first thing you should be looking at is some clutch work. It should bring back some, but not all of your bottom end.

if you really want to wake up the motor after that, then you'll be looking at the CDI box and an exhaust system. But the tire kit will destroy the stock clutch on any machine. Especially 30".
