wideband

[BOOSTIN-BAYOU]

I have a powderlites turbo my problem is my wideband reads 16 when I peg it but I can let up and peg it again it cleans up and runs 13.6 with 10lbs of boost and when I turn my boost controller up it pops and goes to17 when I peg it

10 pounds and 13.6 is a time bomb... I'd be turning that boost all the way down till you can narrow it down. What fuelling are you using? RB? I'm unsure what all PL does in their kit, but I'd be checking boost reference lines to the box, fuel regulator any other supplied units. Has it just started acting up, or you change something and now it acts up?

I thought I had a bad wide band sensor so I changed it out and when I went to change the oil this year it was milky flushed it out seems to be ok antifreeze is perfect I took it out today snowy day with lots of fluffy stuff barely got down the trail and the wideband goes to three bars with that came running poorly so then the wideband went to ten and seems like elevation changes it and my intake was icing up
