Hey all, i have been looking into the dialbo sport tuner and just read that it can shut off the two rear O2 sensors.. will that make the truck run uber rich like when the O2's are bad or will it just run of the front two without a problem like the older model trucks?

 

If the programmer shuts them off then it will probably trick the computer into thinking that it is giving a good reading and that will allow the programmer to alter the A/F mix and that is where you will get the power gains. I would check with the company to see if it will mess up the trucks computer and if they will warrenty the programmers effects on the truck.

 

Most people turn off there rear o2s so do most tunes.

 

that means you could straight pipe your exhaust then, without having to install dummy sensors!!! sweet! im going to get that!

 

Yep long tubes dont even have a place for them but if yu go stait pipes you will lose some power a notice it you will want some kind off back pressure If I were you id go with a dump of you spend a few bucks you can get a good one.
