Car "farting out" under boost !?!?!?

'OO GTP keeps "farting out" whenever I give any type of agressive acelleration. Initially, I thought it was a fuel pressure issue. Since I changed the Cam and crank position sensors the vehicle is running better, and I now see that it only bogs or "farts" under boost. It is as if i can't get the smallest psi of boost before..."FART"! What gives?:confused:
 


any codes when this happens? vacuum leak? plugs? wires? MAF? plugged cat? ICM? do you have something to scan with?
 
New icm (about 100mi), newer plugs, newer cat(less than 2000mi) I don't have a scanner. It only happens under load (while car is in gear), primarily when attepting to pass, going uphill, even pulling away from a stop light. I can go for the vacuum leaks. I know that there was a fabricated jumble of mess coming from the fitting (vacuum?) extending out of the intake at the base of the SC. I don't know exactly how or what part that is supposed to be there but I created a T to connect two vacuum lines that were taped together in the fabricated jumble of mess and connected it to the intake. Don't know if that was correct, but that's what I did!

GO out get a cheap set of plug wires.
What you are seeing is a classic sign of bad plug wires or even a wire that was not fully on
 
hehe.... still giddy from this one - had the same problems... after single plug had been squashed, I replaced all plugs with iridium... didn't know any better :P and then it started "farting" under any boost. At my wits end, was told I probably had a vacuum leak. Then sat and had a beer reading this post and said nuts with it - got $30 wires (lifetime warranty), put them in, and oooooh babby!!! =D haven't felt that pull since my last modd =D

Sorry for doubting, didn't understand that more compression == higher resistance ;) yep, energy was finding an easier ground.

Cheers,
Love the forum ;)
