Newbe Truck Questions

[buttodal]

I'm ready to buy a V2, but I have a couple of questions that have yet to be answered.
* Will I still need to use "sim" module to emulate the rear O2's? I know the cat effic codes can be turned off but I don't want to screw with the exhaust system each time I want to go through NYstate inspection. I have several customers in the same predicament and we all have had problems with cat effic codes even when using a sim.
* What is the largest tire diameter that can be plugged into these PCM's (01-06 Silverado)?
* Will the IM flags still be read in the normal manner, or will they simply dissapear after the PCM is programmed to not use the post cat O2's?

1. No you dont. Just every time you go to inspection, they will have to turn them on. Then turn them off later.
2. 195/30/17 to 420/95/24
3. Im new and have no clue what your talking about.
