Wondering if any of you out there could assist with handling this topic, I am very pleased with the modifications I have done thus far and just trying to finish the upgrades with focus on getting more fuel efficiency out of the vehicle.

 

Vehicle Current State:

 

2006 Dodge 5.9 2500 Mega Cab

Edge CTS Tuner - Low Boost Setting on 1

4" Exhaust from Turbo back with 36" resonator

Stock Wheels and Tires

Stock Airbox - This should be good to 450 Raw HP

 

Currently we are doing heavy amounts of traveling with a 9.5 foot Cab Over Camper and 4 Place snowmobile trailer through pretty mountainous terrain. All the infrastructure is in place to handle these items from a airbag, tie down, and steering perspective. This allows the truck to remain in good riding height while traveling....which is normally around 70 mph as we are slightly inpatient

 

Current MPG Loaded - 13/14 MPG

 

Any insights you have is appreciated.

Injectors

Injectors

 

 

From what I've read......................it's been 50/50 on that at best...................because of the added "oomff"; they use it.......and the potential of better mileage is negated!!

Yep, read into that too.

 

You know if your injectors are leaking if you taked the tack up to 3 k (when engine is warm) and watch it come back down. If it doesn't come back smooth and hangs at all.....you got leakers.

 

Otherwise for the injector change, if you keep it in the exrta 40 hp range you don't seem to cross the threshold of more fuel efficient and too much power/fuel consumption.
