There is an OEM speed limiter of 95mph. The stock gearing of 3.73 could take the Duramax to ~140mph depending on RPM.
The Chevy Duramax has an amazing top speed of 140 MPH. The Chevy duramax is pushing 350 hp. with 6600 flbs of torqe at 3200 RPMs u can disable it with the PPE Tuner Or Efi Live.
Duramax is a diesel motor. Most diesels have a built in governor to keep the engine speed from going too high. I suspect that the engine is hitting the top speed and the governor is kicking in just before you shift.
