Tuner vs. having ECM tuned

Postby Dumpster Guy [OP] » Dec 13 2019, 1:03am

I want to get more Torque from my 6.0 L. Has anyone used a hand held tuner vs. having there ECM retuned ? I want to get the best bang for the money. My motor needs some help. runs great but suffers greatly when pulling my gooseneck roll off trailer. My truck has an automatic and 373 gears but pulls like it has passenger car gearing. Any help / opinions will be greatly appreciated.
Thanks
Garrett

If it feels that bad a tune isn’t going to help.

Well with a tuner, you can have a couple tunes. 1 for towing and 1 for regular use. Lew could hook you up with that. Once you purchase the tuner, you do logs so he can see what your truck is doing and adjust from there.

Vs having ecm tuned...your stuck with what you got.

For a gas vehicle you really only have one tune, it's not worth having multiple as it's not convenient to switch them like the diesel, and probably wouldn't be much difference between them anyway.

The HD trucks are detuned quite a bit from factory, so a custom tune is beneficial and unlocks some power. It's not like a huge difference especially in a huge heavy truck, but drivability all around is improved for sure.

I think you would get more bang for your buck if you re-geared. Especially if your pulling. 4.10's or 4.56's
