That's too bad your still having issues. I feel your pain, i just now have mine where I want it. Mine will idle around 14 and if I hit the throttle it will drop it about 12.5 ish depending on amount. It sounds like a tuning issue, but hard to tell not seeing it. Maybe a dyno session will help...

Wow that would have been awesome to find.... glad you found the issue. Have you run it after the fix?

Hey Nytroed, when it cuts out does it die or just falls on its face? At least you know your running lean, what Afr does it get to? In my opinion if it was a fuel pump it would be acting up at different times. A buddy of mines turbo 800 had pump issues and it would just die out of nowhere, you...

I got mine from a dealer, he had them lying around from an old turbo kit. I would try Hurricane performance in Canada, I know that the use 430cc as well. Or you can go with a boost it set up, I know allot of people are happy with them.

I here you on this. I’ve been thinking about this for a while but can’t think of much else you haven’t tried. As for what Yamadog said, I agree and the jetting is a huge pain in the a**. Have you ever thought about putting an EFI from a later sled on? I would think most of the harness; TB's...

So just a few questions, now does the seld shut down at same throttle position and boost every time? Have you checked for a vacume leak? How much boost are you running?

* wrecked the plugs.

I would do a leak down test of there was quite a bit of water or a sweet smell in the exhaust. My nytro started to chug bad when I started it sounded like it was running on 2 cylinders. For a bit then run fine. Got worse every time I would start it then went down to one cylinder. Changed to new...

Hey sorry for taking so long, I've been out of town. Yes 430 are bigger, stock are 330's I belive. I Tried the plugs first. When I first started testing I made the oil return to small so the turbo leaked some oil into the intake and caused my plugs to fail and the nytro would not start. I had...

Just to let everyone know, so after tying to find every electrical issue on a nytro and making differnt maps for it (lean and rich) I've found the issue. The stock injectors where cutting out at boost. Not sure why they where, I had a feeling after watching the afr and after one run I saw it...

First off hello everyone as this is my first post. Here is the issue, sled runs strong at 1/2-3/4 throttle but if I go to full it will cut out. Rolling to 3/4 then punching it to wot will cut out right away. Going wot from a stop it will go for a few seconds till hits around 5# then cut out...
