yes while i had it all apart i did check it and it looked fine
I dont have a/f gauge, im running a mcx rear mount turbo and it does not have a adjustible box.I will check my plug caps.Is it possible that the mcx fuel box has crapped out?
What brand would you recomend?And where to buy one
Im gonna give it one more shot at fixing this thing,but if i cannt does anyone know of a good shop in Wa to take it to?By the way i live in yakima so closer is better
yes the box can go bad. have you checked the tps settings? had a prob with my mcx box and found it while testing the tps. I would set the tps and then just watch the numbers wonder around. closed throttle, sled off, key on, set at 16 and the numbers would walk up to 21 or so. next I unplugged the mcx box, reset tps and the number would stay at 16. changed the mcx box out and life is good again.

did the head look deformed at all allot of guys had probs with warping the ti headers.i know a few guys that were getting water in there box & causing probs make sure there isnt any water in it.is your yammi gauge pod throwing any codes.
Ill check the box again,no flashing on any of my gauges.
Well i took the fuel box off and opened it and it was wet *** hell,so ill dry it out and try again.Is it possible the water has ruined the box?I am going to relocate it to a dryer spot and put it in a plastic sealed box.
I had exactly the smae problem with my sled last year, I switched the MCX box off of a buddy's sled and it fixed the problem. I then sent mine back and had it reprogrammed. I haven't had the problem since.
