This kind of sh-t gives cors187 a hard on.
Turbo charged Lc4's.
I would take a guess you're running out of fuel when in boost. When you have all that gear hanging off the side of it guess work is very risky. I would be getting on a dyno or at least hooking up some kind of sniffer in the exhuast to see what it's air/fuel is doing. You could be blowing out the spark as well under boost.

Cheers guys ! I did read about the plenum to hold pressue between intake exhaust (not sure bout that exactly ) i will work on that. I did check AFR through the power commander i do have an auto tune set thingo on it aswell. I wouldnt mind getting what i can the best way before i take it to dyno too !

I don't have any ideas on how to fix this.

However, I would like to add this to the list of potential problems I could have with my Duke, so where can I get a turbo kit for my 690?

No stress ! So i built mine myself out of boredom i have never built a tubro anything before so it has been fun learning !
Well darn! That's super cool you built it. I love that you even did a little intercooler.

Do you happen to have a build thread or anything like that? Care to share specs, parts and where you sourced them? I'm highly intrigued!

EDIT: I found your thread on supermotojunkie.com. Reading...

There was one for sale on the sunny coast a couple year back. If you had put this post up back then we may have been able to pick his brains.

I kept a picture of the bike as I was stirring up Cors187 with it.
**** i was late to the party !

All good after some research definitley need the plenum and just some trial and error. If the bike dies in the process it dies..😎
