Avalanche said:I am a long time Cummins enthusiast and owner of Avalanche Engineering in Bayfield, Colorado. We specialize in custom Cummins installations into trucks and off road vehicles. I personally own a 1998 Hummer H1 and installed a 12 valve Cummins in it, ATS Stage 4 4L80E, TST Fuel Plate, Aurora 3000 Turbo and soon to be installed WaterBoy methanol injection.

DWitcher said:Steve, you say your top speed is limited with a 2.56 R&P and 1.96 in the reduction boxes. How about tire size and RPM vs MPH at top speed? Thanks.
BTW did ATS give you a max input spec for the 4L80E?
