Spring Break Trip Completed

[factoryflood]

On Jan 19, 2012 I picked up my '12 CCSB Lariat and was immediately impressed with everything except the fuel mileage. The truck has the factory 20" wheels with the 34" tires and 3.55 gears. Stock I was averaging 16.8 mpg hand calculated, which isn't horrible but my 05 Sierra 1500 with 33's was seeing 16.5 hand calculated, so I was slightly disappointed.

360 miles later, I pulled the trigger on a Spartan Tuner and 4" DPF delete. With the delete and tuner I was seeing 22.1 average highway mpg hand calculated and 18.4 mpg mixed hand calculated. I was much more pleased with this and happy I went with the tuner.

Over Spring Break I finally got a chance to haul my race trailer down south. I pulled my 8.5x20 haulmark race trailer loaded with 6 motocross bikes, 1 street bike ('07 Suzuki GSX-R 750), generator, pressure washer, tool boxes, gear, and other items totaling 8,100 pounds from State College, PA to Tuscaloosa, AL. Averaged 15.1 mpg hand calculated round trip.

Overall I am extremely pleased with the truck and the fact that it didn't flinch on even the largest of hills while passing cars

If anyone is on the fence about tuning/deleting their truck I highly recommend it. Just be prepared to buy tires, cause the stock ones aren't going to last long

The fuel mileage will get better when truck hits 50k and then even 100k. Diesel take a long time to break in.

what hp tune are you runnung?

Towing running the 120 tune as per spartan based on the fact that my trailer isn't "that heavy" for these trucks. Heavier trailers should be using the 80 hp tune.

I'm pretty sure the truck is broken in long before 50K miles, otherwise the EPA wouldn't let them on the road.

Modern technology and all the fuel injection -engine sensors changes the game.
We don't have racks or mechanical injectors anymore.

Everyone is open to their opinion! Diesels take forever to seat the rings and be properly "broken in" My 06 DODGE 5.9 manual says if you dont pull heavy with it early in life it could take 30k+ to properly break in.

Man, I am glad to see this, I have been on the fence about programming an 11 with spartan, majority is H&S, but I have the Spartan already, now I just need to sell the 08 and find an 11
