You need an uprev protuner or another software (ECUtek?) that can adjust VVEL and almost definitely fuel and spark too. I would NOT drive it too much until then.

EDIT: Fixed your link --> Link : 370z exhuast jun camshaft 282 issue !! Are this problem ?? - YouTube

Flash the car with the OEM Uprev Patched Rom. It can be downloaded through the Rom Editor.
This will Fix 80 to 90% of the issues. Since your Z had 600cc injectors an you put back in the OEM ones, this through off the fuel multiplier and scaling.
Doing this will pretty much put it back to Stock other then the the Patched ROM.
This should enable you to drive the car to get it all sorted out with the new cams.

Where did you get the cams from? I would like to get a set

Navyboy916 · 05-29-2014, 01:49 PM

Did you get the buckets replace with a different size due to the increase in duration of the cams? This has to be done so the valve doesn't hit the piston. I have the JUN cams and have no problems. These are not just drop in cams. You don't have to get a retune right away because JUN made these cams to run on the stock program so that's not your problem. You really need to make sue the intake side is still in factory spec with the VVEL actuators. Go to the dealership there and tell them you need the VVEL actuators reset to factory cause there is a long procedure they have to do in order to reset it. I was there for my entire build so if any other questions please ask
