Sounds very good, and yeah you can't wrong with PHP tunes either, Bill is one of the best. Good luck with the Tranny build too.I actually am doing a tugger kit at the same time. Trans seams like its in great shape. Fluid isn't burnt and has been changed several times. Only has 110k shifts great. I'm running php right now and I love with with stock sticks. I wanna keep the tunes a clean as possible. I typed in reviews on google and a lot of cummins guys are running one and they are in love with this tc.
Yeah triple disc is what I would suggest you go with. At your power level you won't have to worry about snapping shafts. The Stock shafts are actually pretty durable and seem to handle power in around 500hp/8-900 ft lbs of torque pretty well..I'm thinking I need to go with the triple disc from them to be on the safe side. The single is only 350 hp and 700 torque. Kind of worries me since I'll be around that ball park. Also have the choice of low stall or non. Can't low stall snap shafts?
