I'm sure this has been a thread on here somewhere, but does anybody have or used any of the banks tuners on the ecoboost yet? Any info will help, I put a afe stage 2 cai on my 2012 eb and the check engine light comes on for about 3days and stays off for about 7-8 days then comes back on. I was hoping to get a tune to fix the problem as I don't really know much about this stuff.

 

The CAI shouldn't cause that. And banks is the laughing stock of the diesel world and I can't imagine it's any better for gas engines.

Double check your connections on your intake. Or try putting the stock one back on and see what happens.

 

Lol...the truth!!
There's much more reputable programmers out there for the ecoboost. Do a thread search and you'll find a wealth of information on these forums.
