^^^nevermind. Probably means "No tune required"

 

to the question of the post. Don't need a tune.

 

instead of starting a new post i figured i would just add on to this one

i currently have an Injen Hybrid CAI and a Borla Cat-back exhaust, looking at installing the 1/2 MD Spacer and have been seeing people say that it will adjust itself, need a re-flash, tune etc.

i was wondering if there is anyone out there that has a CAI and a after market cat-back that had a 1/2 spacer installed and if they experienced the running lean issue or not?

just wanna get all my ducks in a row before going under the hood

thx guys

 

I have a 5/16 spacer CAI and HKS exhaust and when i dyno-ed i was running just slightly lean

 

hey so i have a 2003 g35 sedan pretty much bone stock for now. just bought a 5/16” plenum spacer and planning to pair it with a cold air intake. possibly a throttle body spacer. when i do the plenum spacer and the cold air, will it be able tk handle the fuel ratios? would i need a tune or would i be safe to reset the battery and run both together after wards with no repercussions? thanks!

 

You'll be fine. However a tune will ALWAYS make the car better.
