I want to install my Pypes Offroad X but dont have lots of time to get a new tune done at the local speed shop. If I run the tune from Demolet for awhile will it hurt anything? Thanks in advance....

Semper Fi,

It won't hurt, but your CEL will come on in the dash until you get the rear O2 sensors turned off in the tune or buy MIL eliminators.

 

+1 what tom281 said. Although it is possible that the rear o2 sensors are turned off in the demolet tune already. When i spoke to demolet before, he said he has a guy from sct that writes the tunes on his cai/tuner package. Alot of tuners will turn the rear o2's off in there base tunes even if it's only for an intake.

 

Cool! Thanks all! I guess I will find out tomorrow. I will be putting the pypes off road X on to my existing SLP Loudmouth....cant wait to hear it!

 

Thats going to be crazy loud, not like thats a bad thing though .

 

I've ran my offroad-x without ever turning them off, and never got a code.

 

WOW! That is loud. I was used to the sound of my old stingers on my 03 cobra but this is crazy. I am grinning from ear to ear as I scare people driving down the road. Not sure how long I will stick with this combo but I know I am not putting the stock H back on. And lucky enough to this point, no check engine light. Hopefully it will last! Thanks all!!!
