I thought quite a few guys were running the 858 outta pincher? Doesn't the dealer have a set up?

theres a few with the 11-13's done but they changed the map on the 14's and not as many out here running them. It seems strong from 6500 on but from 4-6000 is really boggy and makes it hard to get going again. trying different things but I don't got an AFR gauge so i'm kind of scared to start playing

From what I've been told from guys that have 13's and 14's is that the numbers are the same. I know that My '14 is using the same numbers as my buddies '13 (both with the drop-in kits) and all is well. I don't think mapping changed so much from 13 - 14, but the wiring harness did. Just what I've been told. Lots of 858 threads on Snowest though.

So fare with my 858 I have had to drop fuel number pretty hard in the lower RPM ranges. I can't make Kalseys fuel numbers and the more I lean it out the better it runs. I am going to Kakwa this weekend and will be playing with my maping and I am running a AFR gauge. I will try to report my numbers after the weekend.

Everyone in Alberta with 858 please post your numbers and lets try to make the best map for Alberta BC.
