So I finally Got my stock front off and put something a little more appropriate for all the $$$ I've dumped into this car.

But my AEM EUGO is showin that I'm gettin 10 or lower A:F now, previously tuned at 11.5-11.8. This HAS to be due to A. The new openings, and B Colder weather.

Do I need a retune??? =\








PS -- Also taking advice on how much to drop this thing... that bumper is looowww....

 

what ems are u using

 

Neither A or B. More colder air would lean out your a/f not richen it up.

 

depends on if he is using the temp correction on the UTEC. It might be overcompensating now

 

+1. I'm getting my car today and I just switched to TopSecret, I'll see if mine overcompensate. Either way it just a few adjustment in Utec to correct them Not sure if the OP uses Utec though.

 

if the cooler intake air resulted in a change in boost it might have put t in a load site section that it is not tuned for and causing the changes in af

 

its an old school unichip from an aps kit... /shrug. I'll retune it with a vb upgrade and when I turn up the boost
