Was wondering if I added an intake how much will it affect my tune and afr. I previously had it tuned with a stock intake box that was gutted at the time being to get the car up and running how much will it affect it now to run without a retune on an infinity? Any help would be appreciated.

 

Tune? By whom?

The ECU should handle small changes like you describe. Your tuner can tweak it more.

something as small as a intake wont effect the tune enough to worry about. You’ll be fine.

 

The infinity will be able to still be able to find your target lamba. Id still do a PC a log and send it to your tuner for any fine adjustments if necessary.

 

Ok thanks everyone
