So I finally got around to installing all my breather mods and my CEL came on last night on my way home from work. got the code pulled today and it said it was an emissions leak. i'm pretty sure theres no way any bolts have loosened or gaskets have burned up so i'm thinking the increased airflow is too much for the stock ECU settings. I'm getting an Osiris dyno tune at a very renowned shop in houston as far as tuning VQ motors go so i'm in good hands but is there anything i should be cognizant of while i'm getting the tune? anything to look out for? ask for? etc. any help would be awesome, thanks!

 

I don't know about some of the technical things he's going to do naturally in order to squeeze more out of your car... but if they'll let you stick your head in for awhile so he can walk you through HOW they're actually doing what they're doing that might be a good learning experience for you. I learned a lot more about what the guys in here were talking about when I got to see how it actually worked.

I don't mean sit in there for 3 hours with him- that's like writing with someone hovering over your shoulder... but if they're obliging get the tech to walk you through some of the interface so you can better understand what's happening.

 

The two error codes I got before getting a tune were due to a lean condition and my front right bank sensor was wasted which eventually destroyed my HFCs....so I was told.

you should get an mrev 2 b4 tune, i dident see it in your list of mods.

 

Having read his profile I'm not convinced he is MT so he wouldn't need the MotorDyne MREV2. He does have Infiniti branded valve stem caps....

Lol I know the stuff I listed got pretty nit picky:P but yes I have a 5at so no mrev for me
