We have a blog on the best performance mods for your truck and as you can imagine tunes definitely made the list. We listed the top 5 common uses for them here. However, we were curious what other ways do you guys use your tuners on your truck?

 

You mean, aside from *everything*?

haha

I like to use it for data logging and watching trans temp; when I'm not using it to make a bajillion whp

 

I use mine to draw lines down the street

 

To change the rear differential gear ratio, tire height, RPM and to kill off the erroneous reporting of systems that don't exist on my swap vehicle.

You were rolling for a while there brother I like it!!!!!

 

changing tire size, changing a couple body control module functions, swapping fuel/timing on the fly, monitoring/storing parameters that even the fancy upgraded dash doesn't have, reading/clearing diagnostic codes, data logging... and probably a few things i'm forgetting.

epic! i need a new clutch before i could pull that off

 

I use my tuner to change the radio station. The calibration tool on the other hand...
