Friend's Duramax is in bad shape - 2000 RPM limit
Are there any good web sites like TheDieselStop for the Duramax?
Friend's truck won't go past 2000 RPM once it's warmed up. 2000 RPM, all gears, that's it.
Dealer has replaced a bunch of stuff and now wants to replace injectors. They have no idea why it's doing this.
