Custom tune for stock h pipes/high flow cats?
Posted: Mon Jan 19, 2015 12:53 pm
Here is what I have guys. 05 mustang GT, Ford racing CAI, axlebacks and a 91 octane predator tune.
I want to weld in high flow cats to my stock H pipe. Will this require a custom tune? If so why?
Would really appreciate a response. Thanks in advance.
