Hello from Missouri

[Jethro]

Recently purchased an '07 Sierra Classic LBZ. Thrilled with it thus far other than I lost a couple of glow plugs already. Has a 4inch straight-pipe exhaust and some kind of tune for sure; it has a 2-position switch in the dash and it rolls a fair bit of smoke when i run it up a bit. Bought it off dealer lot in Texas and haven't been able to determine prior owner to ask about the tune. I stumbled on this site but love what I see thus far and will surely be a regular customer.

Welcome friend. Sounds like your truck has some tuning already installed.
