Ok, i did a nice engine build where i got a ls2 lower unit and installed ported LS3 heads and an escalade intake installed...I would like a little more air to go inside the engine, but i feel my stock tb is holding me back...Its a six pin just like the LS2/3 but neither the LS2 nor the LS3 tb work on my tahoe...

No movement, just a reduce engine code.

Does anyone know what wires i have to change to get the bigger tbs to work on my truck?

The torque rush will not work for its for the old 8 pin to the new 6 pin...I am a 6 pin that probably needs a few wires swapped around...

Your post is a little confusing to read. So you have a 2010 Tahoe, with a built LS2 ?

Did you swap the reluctor wheel on the crank? . . . any more info on your setup?

If you already have a 2010, it should already have the 4 bolt TB on it with the brass TB blade

Sorry, allow me to clarify...

The engine is a LS2 with the correct Reluctor wheel on the crank and i evenhave the Compcam Phaser, 4x cam sensor, and 4 bolt TB with brass blade...

The engine runs fine, but i would like to put the larger TB on it. I tried the LS2 with the silver blade and it didnt work. I even have the LS3 TB with the brass blade and that one is also not working, giving me codes where the low and high are not correct.

I noticed the rear opennins on the LS3 and LS2 TB are larger than the stock truck ones which will allow my engine to pull harder up top...
