I have a DiabloSport Powerpuck for a Dodge cummins 1998.5-2002. This chip adds up to 50hp and 125 ft/lbs torque. I also have a BD boost fooler for 1998.5-2012 Dodge cummins. I have had these for about 3 months and I upgraded to a larger chip. These chips really wake up your cummins! More details can be found on www.xdp.com. Email or text/call if you want more information. Items are like new.
