Just bought a 96 Dually with a 454 vortec. Im looking to cut the cat(or cats) and run a true dual setup. What is needed to do this to get rid of the rear o2 sensor? Would be willing to go with a tuning soft ware id so. We have HP tuners for f bodies and tuner cats for OBD1 fbodies, Im sure one of these wont do it.
Thanks

 

Used to be tuner cats did it, but then they sold out that part of there software to Jet. There the only ones who do the older Vortec stuff.

 

Yep,not a user friendly software either.LOL
If hptuners or efilive is hard for some then tunercat or jet is alot worse.I promise

 

yup like wheatley said tunercats was good for the older vortecs but it is a pita if you dont know tunning.

 

Where can you get the tuner cats for it? Like I said we have one for OBD1, and yes it is a bitch

 

well it is now the jet spectrum tuner.Tunercat sold to jet,same thing except ithas jets name on it

 

I think that there are still people selling some ever on tunercats site but it may be hit or miss.

 

Can those '96 engines be upgraded with like a '98 vortec pcm?

 

If you are goin to upgraded,then go with the 0411 PCM which is 01-02

 

I have a Tunercat OBD2 with MXScan that I will sell to you. The definition file I have is for 2003 - 05 LS1 Trucks (4.3L, 4.8L, 5.3L, 6.0L, 8.1L) and is OBD2_04.

You will need to buy a definition file from Tunercat for 79.95.
OBD2_07 for 1996 - 97 Vortec Trucks (4.3L, 5.0L, 5.7L, 7.4L).

PM me if interested. $480 plus shipping from Canada.
