So i have flowmaster outlaw axlebacks airaid CAI ,throttle body spacer just installed a set of bbk shorty headers and car was runnig awesome for 5 days then it started misfiring took it to the dealer could not find anything after 4 days said it was misfiring but it was in the programing and they are blaming it on the headers apparently the pcm or computer is always learning and sensed something and tried to compensate and thats the problem anyone had any issues after installing these on a air density motor?????

I put headers drop in k&n filter and high flows and I have been having problems ever since with misfire and engine light, Guy from ford racing told me itll need a tune to fix it.

Can this happen to me cause I want to put a borla atak catback.... Will I need to add an air intake ?

Axle back wont cause this. Or a intake for that matter. You dont need a intake when you do axle backs

Will I need one for a catback or it's the same as a axle back? Thanks...

Guys have done catbacks with no issues
