Waiting on tunes from your tuner?

Some of the most comforting words in the world...


Tuned by "The Viper Whisperer" Sean Roe.

yes it can, i have no cats and no CEL


Are all the O2 sensors turned off or just the rears? I know the SCT can turn all the O2 sensors off but the question is can it just turn the rears off?

Is there any problems with the engine if you turn all the O2 sensors off?
 
I posted this on another thread this morning, but felt it appropriate here also.




Took some prodding, but Marty sent me a tune for my truck a few days ago and on the Dyno in TN today Fatjack,Roz, And the Dyno folks said that my numbers were exceptionally impressive for a QC. :rock:

The torque shot to 490+ at the start of the graph and stayed like that until red line. :rock: :burnout:

HP 400+ with max 437. My truck only has Stinkers 4"exhaust, Amsoil Turbo Deisel microfiber intake filter, and Marty's tune. :congrats:

We also thought that the truck having been owned by Elliot Sadler the race car driver may have had something to do with it also.:dontknow:

I dont know if it will turn the front sensors off but you dont want to anyway....the engine will run very rich and rough because the computer is getting no readings...........As already stated the SCT will turn the rears off...all the rears do is check to see what is happening down stream of the cats...it checks to see if the cats are over-heating, stopped up, etc....my SCT tune has the rears turned off...
