Not sure on your elevation. Most of the people I know that have these sleds in AB/BC ride in the 6000ft plus. I use father Climbmax, jetting in my sled. Front mount turbo "CPR" with 2" outlet into a Hindle muffler. 127.5 mains, 15 pilots, 1.5 turns on the screws, dropped the needles. This setup has worked great for me, about 2200kms of boost. Used the same jetting from 10 to 20lbs. Couple of other buddies use the same setup with a bigger turbo and just a straight pipe. I don't have an air/fuel gauge, its coming this summer, so take this info for what's its worth, not much. :D
