Just wanted to give a shout out of thanks to Left Coast Diesel. They just put a Colt Big Stick Cam and an BD o/d lock out. Dropped the truck and trailer off on monday morning and picked them both up wenseday morning for a tow down to Long Beach. First thing I noticed was how quite the truck was. Second was how easy boost came on. Many others have said boost comes on quicker. I would describe it as easier with less throttle to get going. For the first drive I left the truck in the stock tune to get some feel for how things where working. First time with this trailer so no mpg data. Every trailer has a different drag coeffciant. The o/d lock out worked well it was really nice to not be forcing down shifts all the time. Left it locked out in LA traffic and drove it like a manual. Up and down the grape vine worked great. I have one complaint, the location of the indicator light. I cant see it. I need to move it to were I can see it. Should not be a big drama to move the light. Overall I am pretty happy. LCD got the job done on a tight schedule.
