Hey everyone I was just wondering if you need to undo the battery when you drop a CAI in. I put a volant in, I have noticed a big difference but I read somewhere you should reset the system is this what I need to do... this is a 2008 f150

 

Either way, if you don't dosconnect the battery it will still learn, it will just take time. I never reset mine

 

so it dont matter if I reset its a 08 f150

 

so what is the best

 

you need to get a tune.....alot of people seem to run lean with the CAI on 04-up
