As soon as my stage 3 kit is installed, I will post here on my results. Right now i have the stage 2 and it ran strong all last season. i never had an issue with and bogs or otherwise. Currently running 11-62 Polaris weights, and my own combination of primary/secondary springs. Similar to SLP's recommendation. Fuel has been a mixture of 89 with octane boost, or 91 with boost depending on where I go, getting solid fuel here is an issue. I will also have the dealer check for codes next time I am there
Problem is right now sled is on its way to the dealer for a possible top end, so it may be a bit.
What version of mapping are you running from SLP?
they sent me 70-256 mapping for 2000' range, running the 0-3000' head
I'm also curious, when you did your TPS calibration, how much was it out. I can't remember how much mine was out when I did it (it was last fall), but I know it was out by the same amount at baseline as it was WOT. I want to say .04v, but that could be wrong. I am going to recallibrate it with the Stage 3 instal
