Best combo for improved MPG, less focus on all-out power
So, to describe my truck (yes, I am a complete n00b, but I've been lurking for awhile now)...
My LBZ's engine/trans is stock save for...
-Banks turbo-back with no cat
-EGR block off with electronic finger stick
-Banks EGT and boost gages
-BD driver's side exhaust manifold
All the work was done by the previous owner that traded it in to my dealership...I have not touched the truck mechanically, drove it as my demo for almost a month, and bought it Saturday.
I have been getting 15 MPG when adjusting for speedo error (truck has fresh 285/65/18 Silent Armors)...a 14.5 MPG tank included 100 miles of towing 6,500 lbs with my gooseneck horse trailer. I would like to improve MPG...more power is awesome, but less critical than an MPG bump. I like how this "lightweight" regular cab 4x4 hauls ass
It would appear to me my best option is EFI Live through Rob, while adding an AirDog lift pump. Is this accurate? I admit I may take the truck to the track once or twice to see what it will do, but I have 3 Camaros for that stuff
Longevity and MPG are my 2 most important things. Admittedly, the truck is not a DD, and due to its pre-emissions status, I will probably hold onto it for the next 6-10 years, adding 5-7k a year to the 87k it currently has.
Awesome forum, BTW... I have been on several GM forums over the years, and this one appears to me to be the diesel truck equivalent of LS1 Tech, which is a high compliment IMO....
