What is the biggest size MAF we can run on a 4.0 SOHC with the stock programing? Would it help with performance any? Hurt any?

The truck has a K&N FIPK, and a cat back exhaust if those matter.

Thanks again,

theres really no point to it unless you upgrade the ENTIRE intake tract. that means your new FIPK needs to go with a larger tube, throttle body needs to be bigger and you can either replace the plenum with a bigger opening or have your stock on bored out.

so unless you want to do that so you can lose some low-end torque, go ahead but it truly is not worth it.

 

haha alright, just curious! lol

 

The K&N has is wider tubed than stock. I had a 90mm or 95mm (dont remember) on my truck. Pro-M

 

how did it run? did you have it chipped or was it stock programing leo?

 

Chipped. You know how i roll.
