Ok so I have an 03 350z track. Right now im currently running a stillen intake, kinetix plenum, mrev2, stillen engine damper, and a muffler delete. The idle is a little rough with a little more vibration but nothing crazy (from what I know the extra vibration is from the stillen engine damper) If im in 1st and go to about 5 or 10 mph and put the clutch in, the revs drop down to about 300-500 and almost acts like its going to stall. Could these make my car run lean or rich? And would doing an uprev tune fix the idle and somewhat almost stalling problem?
P.S.
Still planning on getting art pipes and tdx2 so if the tune would fix it how bad would it be keeping my car the way it is until everything is put on because I don't want to tune it now and than re-tune it later.

for fact car needs need a tune to make sure car is running good. However with the mods you have right now shouldn't be doing that. I had almost same mods just with a borla exhaust and my car never had idling issues. You should start looking for a vacum leak. It might not be a big leak since you don't have your service light one. good luck.

My G had a similar issue with the idle dropping when I let off. It ended up being a dirty throttle body. Get a gasket, unplug your battery, take it off clean it carefully, reinstall, do the resets and it should be fine. Good luck
