    Hey, I have a bone stock 2009 LTZ (at least that s what the badging says, VIN check says COMMERCIAL TRIM?) but its loaded (ie. heated/colled front seat, 4 captains chairs, rear captains are heated and power fold, power rear gate, power/heated mirrors) and tow a boat. What can I do without breaking the bank to gain some hp/tq to make the long hills and pulling the boat out of the water a bit easier?

    TIA

    What Pete said, that's your biggest bang for the buck. If you physically delete the AFM system, a new camshaft with the appropriate tune can yield another 20-30 rear wheel horsepower. The stock exhaust can handle plenty of power though long tube headers do help as well.

    That may have been a livery car

    It would be interesting to see the RPO sheet and decode the VIN.

    That was the only thing I could think of bit still seems odd it comes up as commercial trim. The insurance a D dealers run the VIN and ot returns as an LS.

    My wife took the Tahoe this morning but when she gets back I'll post a picture of the RPO. The VIN is 1GNFK13049R244384

    I was just on their website. Is the $600 (Autocal) worth a mild tune if I don't plan on cam swap or force induction or anything like that?
