I own a 2003 350z with a Stillen Stage III SC. Picked it up a couple of weeks ago in Florida drove really strong and smooth. Then the cold came here in Delaware and car started to run rough. Think it is running lean need a good tune shop that someone has used and trusts. Let me know looking to be aroung north MD-south PA.

 

RT Tuning in Lansdale, PA.

Get the UpRev Osiris Tuner, too.

 

There is no tuning that can be done on the stillen as it has a locked tune and the fmu unit cannot be adjusted in any way.

 

Good info. My mistake. I guess that's how they can warranty it to a certain extent.

 

Do you have an a/f gauge...if not i would get one to see were your a/f is at.

 

lol and another time u will realize...dude u should have done some research i actually might feel bad the situation u got urself into...u cant even tune the car with that kit..lol wow, i cant beleive u didnt know this and got urself into that car...
