I am sure theres aa post somewhere on here about this but couldnt find it. If I was to remove my cats do i need to turn the o2 sensors off in a tune, what about the temp over air also? also if i remove them and the ses comes on how can i bypass the o2 sensors to turn it off? thanx

 

You have to get the rear o2 sensors turned off in the tune or run simulators.

 

can this be done if you have a store bought tune ie superchips or crane?

 

Nope the handhelds cant do it except for the brand new predators I believe. If you have a handheld you have to buy O2 simulators or get a custom tune. My advice put the cost of the sims toward a custom tune and sell the handheld on ebay and get you a custom tune oyu will be alot happier person trust me I had a hypercrap on my truck for two weeks and got rid of it.

 

right... but can the other tunes be used as a base...for example, I like my Vinci/Crane tune, but would like to pay a tuner to turn off the rear o2s...is that possible and still keep the Vinci/Crane tune?
Thanks,
Damon

 

Tuners can tune it how ever you want. If you want to pay full price to have them turn off the cats, thats your choice.

 

Waitforme will probably turn them off for free or next to nothing if you send him your pcm and pay shipping. Jesse is a great guy
