johnjr 04-24-2009, 09:05 AM Does anybody make a tuner for a 7800 275hp duramax? My father has a 5yd dump and its a dog! He bought it off the lot thinking 275hp would be better than the 237 hp Mack it was replacing. Not even close! The Mack has so much more torque. Truck is 05. DURAtotheMAX 04-24-2009, 01:07 PM I think TS Performance makes something for the 7.8 Dmax. ben trwtow 04-24-2009, 08:43 PM x2 on the ts bought one for a cat worked great thanks terry a78turbo 05-05-2009, 02:35 PM Anyone know if EFILive will access and tune the 7.8 ecm? I was thinking about trying to tune one also. EFI Support 05-05-2009, 07:44 PM The 7.8 uses a Denso ECM, we've got an ECM here and have had a brief look at it, but unfortunately we don't offer support for it and don't have any immediate plans to support it.
