Attention: TDR Forum Junkies 
Have a 2003 3500 dually quad cab, long box, 2wd with 48RE, HO and limited slip on 4. 10 gears. Towing a HR 36' Presidential with 4 slides. Of course wanted more power. Had Brothers Diesel Performance install PowerMaxCR adjustable with digital guage package. Clean installation, The box performs for me, I am a Happy Camper. Next I will take the brother's (Eric and Ryan) advice and upgrade the intake side to keep things cool, give the 48RE some converter help and be ready for the western mountains. This rig pulls great now - we love it in the Smokies and look forward to many trouble free trips. Thanks to Brother's Diesel Performance and TST.
