I have the speedwerx can and intake on my 08' m1000, I want to put a a y-pipe on but was told that I have to have a fuel controller box because it will run to lean. Is that true? What have you heard or done?
y-pipe and can really require a fuel controller?

All depends on the elevation and weather you run 91 octane or higher. I have ridden with a couple of people that run a y-pipe without a fuel controller. It works just fine, but every sled is a little different. Keep an eye on your plugs and you should (IMO) be fine.

Burned my 07 M1000 down twice just trying to run a pressure regulator at 51psi. So IMO install guages first. Check your temps. Install mods and watch it.
My guess is you will need a box/controler.

i have an 09 1000 with a can and speedwerx y-pipe....i ride 7-11k.....any kind of a long climb will put mine over the top of reasonable egts without a fuel controller.....i use a bd and use +7 to +8 on the top end fuel, 7200 and above rpm.....over the top egt for me is about 1370 on a short pull and about 1325 on a long one (over one minute wide open)...my egt probe is located about 2" downstream of the pipe/y-pipe junction....without adding fuel, the egt goes quickly over 1400 and i'm already out of the throttle as it does so....this is supported by plug readings and piston wash.....soooo, i wouldn't run a y-pipe/can without fuel, although i know some do.....and some that wish they hadn't.......
I had to add up to 56psi to keep temps down at 5000ft, and it can change at diff alt and air temp.
