89Z24 Posted June 20, 2015 Report Share Posted June 20, 2015 I've got a 2004 2500hd with the 8.1/Allison that I tow my rock crawler with and was looking to get a tow friendly tune to help it out some. Anybody around town that you guys would recomend? Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted June 20, 2015 Report Share Posted June 20, 2015 Does edge or bully dog make a programmer so you can change it on the fly when your not towing? Quote Link to comment Share on other sites More sharing options...
SRTurbo04 Posted June 20, 2015 Report Share Posted June 20, 2015 I would imagine any of the shops in town can do that since its a gas motor. Hit up dyno brian to see if the weight of your truck can go on his dyno http://www.dynotunemotorsports.com/ 311 OPM Companies Drive Galloway, OH^ 43119 Telephone (614) 778-8984 Quote Link to comment Share on other sites More sharing options...
Geeesammy Posted June 20, 2015 Report Share Posted June 20, 2015 Putting a box tune on a vehicle that will be towing something is a terrible idea. Brian has seen ecoboosts come in with lambda set to 9.7:1, so if you want to lose economy and power go for it. I've never had much luck with one of those handhelds. Call Brian and see what he say's, I'm sure he'd be more than happy to answer your questions when he has the time. Quote Link to comment Share on other sites More sharing options...
