THE TUNING PROCESS
PLEASE WATCH THIS VIDEO FIRST :
Once you get your tuner, it will ask you to fill out a this form (https://gdpproducts.com/pages/order-form)
When filling out the form, please use the pre order number that came with your tuner. There should be a piece of paper that came with your tuner OR the preorder number should be on the box it came with.
You will not be able to fill out the form till you have the tuner as that is needed to get the reads of your ecm and tcm to fill out the form.
To get the read of ecm you will need to connect to ecm under the hood. The read for the tcm you can get by connecting to obd2 port in the cab of the truck
save drivers to load to your computer so you can read ecm so you can fill out form and tune truck
