Hi all - Welcome back for the second time this month!

I apologize for the inconvenience of the site being offline. The site was down for technical reasons, but it didn't help that I was of offline for two weeks (camping and travel). Once I got back, it took a while to get things sorted out. That's resolved, and the site is now back up. Huzzah!

Please take a minute and read the Site News thread I've posted in the General section, and feel free to comment. Thanks!

alright so I would first start off by saying I have tried to research this topic but no luck.

so what happens is whenever I try to go into boost the truck just his of sputters and its kind of like a fuel cut but worse. I have tried swapping aim and I just re adjusted my tps. it drives perfectly normal afr are normal when idling and driving. it seems to only happen when the  turbo light comes on the cluster. but on my boost gauge im only able to get like .5 of a pound as soon as that light comes on its a no go completely.

I read some where that the truck knows its going into boost based off the arm and tps. I have swapped spare afms' in there as well. I'm just completely lost and looking for some ideas.

also there are no codes being thrown at all

Check all your plumbing, particularly where the pipe connects to the rubber boot at the throttle body.  Could be that they are just loosely fitted, stays together in vacume, but as soon as you boost it parts and vents massive amounts of air...
