Bully Dog 40420 Review: Bully Dog 40420 Triple Dog GT Diesel Gauge Tuner. I bought this and put it on my mostly stock 06' f-350. The change in power is day and night. the truck doesn't have much lag anymore, better fuel mileage, and it lets you moniter everything (except exhust temp without a probe kit) I wouldn't recommend putting this into a stock truck and running it on a extreme and using a lot of throttle, the 6.0 can't handle it... But for fuel mileage and some more power it works wonderfully.3 of 3 . Full reviews at amazon »
