1999 Chevrolet Suburban
December 2005

After a long search I found this extremely rare 1999 Chevrolet Suburban SLT with a 6.5L turbo diesel on a farm in Saskatchewan, Canada, which I bought over the phone after haiving only seen images on the computer. When it was finally delivered, I was relieved that it was totally stock and in absolutely mint shape. It was exactly the way I would have ordered it - Jet black with tan leather and every option offered by GM that year. The first thing that I did was remove a few stripes and then polished it so much you could read a newspaper in its reflection, then I found a new set of aluminum take-off wheels that had been originally installed on a 2005 Duramax. I also upsized the tire size with a set of 265/75R16's Goodyear silent armor tires. The Suburban was originally equipped with 4.10 differential gearing, so I changed them out in favour of 3.73's. This dropped the engine rpm by about 12%, increased the fuel economy and made it a great highway cruiser. I then started on the performance part by adding a DSG computer upgrade, K&N filter, and 4" exhaust with a Banks dyna-flow muffler. The boost has gone up to around 10-12 psi with peaks of 15-16 psi, all monitored by an Autometer triple A-pillar pod with a boost gauge, pyrometer and a tranny temperature gauge. Future plans include a Diesel Services Group gear drive timing set and possibly a 2-3 inch lift to accommodate 285 tires (the 265's hit the mudflaps now).

I plan to keep this Suburban for a very long time, so I consider it money well spent. For now, I just enjoy the looks and compliments I get, and hope it will last long enough for GM to get their head out of the sand and put the Duramax in the new Suburbans and Tahoes.
