Who hear installed headers and drove it awhile before tunning? Near as I can tell only problem (other than not peak performance) is getting cat codes.

The ARH just showed up,im deciding whether to get cracking on it today. Not sure yet about tuning ,waiting reponse

 

Do it! Nothin but cat codes and shitty mpg's till you get it tuned. Waiting for pics.

 

It's ok to drive it. Ive driving with them on for the last week. Waiting to get retuned.

 

who's tuning it?

 

I love your truck. Just saying lol


You will be fine. Just wouldn't be getting on it. Not going to hurt it, but just wouldn't.

I hope to get my obx headers around the begining of Feb.

 

It's ok to drive but I wouldn't get on it a whole bunch until you find that wideband.. She will be leaner after the install no doubt....If ur running the stock tune not as bad since they come pig rich...

 

So many tuners dont feel wide band is necessary,

 

Must be hard to tune not knowing your AFR...Good luck

 

It'll be fine to drive it as much and as hard as you want. And I'll be the first to tell you that trying to tune WOT without a wide-band is a hit or miss deal. Too rich you lose power, too lean can do serious damage!

Tune it on a dyno WITH wide-band O2!

 

x2!!!
