Silber turbo 7000 rpm bog

[T&A1000]

I have a 2013 pro with a silber turbo and almost 1600 miles. This sled has never really ran right. I finally got it running good at the end of the season last year. I can't ever go to full throttle. As soon as I hit 7000 rpms the sled falls on it's face. Any ideas why? I replaced the exhaust valve solenoid and cleaned the valves and it ran great for a couple rides. Also if I stab the throttle from an idle the sled will die. Thanks in advance!!

Well first i would chechk your tps and then go from there, it is hard to tell for sure what it could be... is your turbo good? Do you have correct fual pressure?

It's kinda process of elimination. Unfortunately. Multitude of things to check.......tps, exhaust springs, throttle kill switch, exhaust valves,doesn't sound like clutching. Just start checking the simple stuff first. I'm sure the gurus will chime in soon.....you will find out what it is. I was always amazed how quick you can hit the rev limiter from 7000 rpm!! Is it the 2013 silber kit? Guys r having great results with the new reflash map on ecu. Including myself.
Good luck?

is it a Bully Dog reflash kit or a fuel controler box kit ?

It's the silber kit with the bullydog update. I don't now if there's any new reflashes. Can't seem to get a hold of Cory.

When mine did that it was the turbo going bad. I would pull the intake and check the play in the turbo.

Here's an update. If I'm just easing my way through the trees at a slow speed the air fuel gauge starts climbing till it goes ----. It bogs really bad if I'm chopping the throttle. If I hold it wide open sometimes it'll run perfect through a good pull, other times it'll start bogging.

First of all please let us know everything you have check out already, it is the prosses of alimanation. Please let us know if you replace fual filter, did you check for boost leaks did you check you tps, did you check all the grounds. At this point i would say it could be the filter or tps.

First of all, check the compression on both cylinders. Change spark plugs.
If it still bogs out after everything mentioned is checked you need a new map, it sounds like it can´t burn all the fuel.
