Does anyone know the top speed for the exp? I installed a Superchips 1715 and a Flowmaster 40 on my '00 EB Exp in Jan. The truck pulls off ok but not fast. It really picks up around 60 -70. It crosses 100 easily and I feel the trans upshift around 90mph. The speedo readout stops at 100 and my needle is usually beyond there. I've used the perf and tow mode with 93 octane, and I do not tow. I know it out runs most other similar size stock trucks like the chevy tahoe, cadillac escalade and chevy silverado.
