1JZ Spooling Problem
As I left work this morning to get something for breakfast a 350z 
jumped on my tail. Thinking this would be a great chance to let him know he bought the wrong car, I punched the gas and started to spool 
. As I started to build boost, my car sputtered real bad (kind of scared me), and then picked up again. Basically fell on it's face 
!?! I thought, maybe just a mishap? So.... I decided to give it a go again and it spooled with no problem. Figuring third time was charm, I took off and it happened again. This is not a consistent problem, but it does make me wonder what the problem could be? I figured maybe the plugs were fouled out? But I just replaced those last week with NGK's and had to gap them at .28 so that the car wouldn't sputter at 10-11 psi. Anyone have any ideas??
PS - I have new turbos with about 40k mile on them, but I want to use these as long as possible.

Do a pressure test, might have a boost leak somewhere! On map based systems you will idle and drive around fine with an intercooler hose popped off; but if you gun it all the boost flies out the system and its basically running NA
