Has any of you guys had issues with your dbw throttle bodies on boost? I have a 2011 Sierra and have tried the stock tb and then tried the ls2 silver blade. Now I have a ctsv tb and it works better than all the rest of them but still having issues.

 

What type of issues are you talking about?

 

Also, what type of boost. I had issues when I was pulling air through the TB with a supercharger, but don't have issues when I'm pushing air through with a turbo.

 

Atomic, I've been meaning to thank you for introducing me to Blake. He has done wonders on the truck. Issues that I'm having with the turbo system is that when it spools up to about 4#s of boost it throws a tps code and leans out. Thats not with 100% throttle. It does it like when I'm pulling a hill. The other issue, if I'm at a dead stop and just floor it, it sends it into reduced engine power until i turn it off and let it sit for about 10 mins or disconnect the battery cable.

 

Put stocker TB on and call it a day

No reason to upgrade IMHO

If still have issues with stock TB and boost with codes get a new tuner

 

Those issues are pretty easy to fix in the tune, Blake should know better than that
