Best Ford 6.7L Exhaust Weight Reduction Tune

It is time for me to reduce weight and improve reliability of my 2015 F350.

I'm looking for a tune that maintain stocks power/torque and has no issues with drive-ability. Don't need extra HP/torque or anything that affects the transmission. I'm happy with stock power and stock transmission.

Please share your experiences.


PS I have exhaust weight reduction on my other diesel vehicle (a diesel Jeep) and it is incredible. Fuel economy is up, power comes on sooner since there is no exhaust restriction, and engine runs cooler. Exhaust soot opacity is at 6.5% versus .9% with the heavy exhaust components installed. State law max opacity is 30% FWIW.

Is "Exhaust weight reduction" a synonym for tampering?

given how obese modern pickups are, the minor weight reduction of deleting your emissions components will be at best unnoticeable, except for the coal you now roll and the diesel stink. Anyway, if reliability is your goal...

Common Problems

with that said typically the biggest sort of issues for power strokes seems to be their EGR coolers, coolant leaks, oil leaks, and turbo failures.

So if increasing reliability is your goal, I'd delete the EGR cooler, and do a minor tune to cut the check engine light. Also don't increase the power much to help protect the fragile turbo.

I have a diesel car, and most of my fuel economy and reliability improvements came from removing the EGR and cooler. I have my DPF and SCR still intact.
