Hey guys. My truck has been running great ever since i completed the swap and is my daily driver. But in the last month or so it has been cutting out if i jump on it really hard. It does it off and on but not all of the time. If i boost it up in second gear and hold it at about half throttle around 10 psi its fine. But if i go ahead and hammer on it it wants to hesitate and it flutters out the Exhaust. That's the best way i can explain it...It Flutters! The boost has always creep up to around 12-14psi but when it is acting up it does it at around 10psi and wont let it climb. Any help will be appreciated.
 
Check your plugs. The gap might be too big.

Also, it may be running lean at high boost.
 
I changed them when the problem started to happen and gaped them at 34 and it did not change anything. I don't think it's leaning out i don't hear any detonation. I'm not real sure what is going on.
 
sounds like you have a boost leak. whats the duty cycle of the wastegate doing? im not sure if you loggin or not.
 
No lag. It comes up to boost fine. Pretty sure its not leaking.
