what are your spark plugs gapped at? usally its not fuel cut your hitting but spark cut...try gapping them to .040 and see if it changes, and go lower if ur running more boost if the spark gap fixes it. did u ever have your tps wiring replaced? check that too cuz it goes out real easy on our cars

 

your blowin spark buddy, get some new plugs and gap them.
this should fix your problem.
what injectors are you running?
What are you using to tune it?

 

il try it i supose but with the 23000 miles iv put on its iv flip plugs in and out of it cuz of working at the shop...never gaped them... then y all of the sudden now? i got a agp waste gate and iv tuned it wayyy down and im blowing spark at 8-12 psi?

Can you over spool a stock turbo on a built motor?

 

it all depends how many pounds its went to.
What's the most boost you'v gotten outta it?
You can blow spark on 5 psi dude....get yer plugs gapd

 

ya iv boosted 15-18 on a reg. with the same plugs... just kinda happened in the middle of a ride like less than a miles from the shop and ya i ripped outta the shop and it was running good

 

sound like a quick fix thats to cheap and easy to work lol?......its like on southpark the cure for cancer is $100000 cash injected right into your blood stream.....cash cures all

 

Ended up being the fuel...put some in a jar and let it sit and theres all kindas of crap in the bottom... i dont know if someone put it there or if something elese happened to get water in the system but now i got almost a full tank to flush and fill *plugs gaped*
