LLY/LBZ ?

[Spag]

I've got an '02 GMC 2500HD with a Duramax...love it. I just bought an '06 with an LLY. I coudn't see the extra money for the LBZ. What's the difference? Is an LBZ just an LLY with a chip?

[madmatt]

Yep...just different programming.

So I can get an LBZ by just buying a $400 chip with the $2300 I saved with the LLY?

Did they beef up the tranny in 06 to take the extra power?

[spongebob]

a 6th "gear" was added.

But that's the same tranny that's on my LLY...right?
