3 Breather Mods, re tune needed after G3 CAI?

Zay370z · 10-27-2017, 01:47 PM

I couldn't find my direct answer, so here it is.

I understand a tune is needed after 3 breather mods, I installed test pipes and a fatback exhaust and got s tune and was running lean, I just installed g3s, I'd like to wait 10 days to pay for the tune, but if I have to get it now I will. Thoughts?

Also is there a way to tell AFR ratios to see if I am? A re tune for me only costs $100, but I'd rather wait.

I would get it asap but you will be alright for 10 days

Just stay out the throttle till then, a bit rich is better than a bit lean.
Some diagnostic tools that plug into obd2 connector will read afr's....unless you purchase an external gauge & plumb it in....they can be pricey.

You'll be fine. The Z can self tune A LOT.
