well see my car was running in limp mode. so i would disconect the battery for a few hours then connect it back and it would run perfect until i turned it off again. well i worked on it or tried to and couldnt figure the problem out so i took it to the dealer.well they called me today and said they have it running now but the fuel cuts off at 4500 rpms. could my utec be in valet mode? i thought valet mode kicked in at 3000rpms.

I don't know, but my has done this exact thing for nearly the last 2 years. I have the UTEC and ProCharger also. SGP Racing tried to correct the problem and thought it had to do with fuel, they ended up putting 720cc injectors in the car. Now they think it is the valve body they put in. I have an appointment in 2 weeks so they can try again to figure outthe problem.....

Sorry, the above was typed from iPhone....
I knew a guy who had this exact problem with his ProCharged 350z and endd up finding out it was a coupling collapsing under boost, so the car was getting too much fuel, not enough air - his supercharger internals were also going to crap... so both of those things lead to his car only being able to hit around 4000RPM like we are experiencing.
Do you notice the smell of fuel anywhere?

i got my tune saved on my laptop also went and picked up my car today now i know what the are talking about. its almost like a fuel cut. when i hit 4-4.5 the car stops getting gas but it happens quickly cause when the rpms drop and i keep my foot on the gas it goes again its real weird.
