Disclaimer: You've just selected the UPGRADE service option for your L5P E41 ECM. This means you need to send us your original ECM. Once HP Tuners upgrades your ECM for tuning, it must go back into the same truck it came out of. If you do not send us your original ECM with this upgrade option, it will be returned to you with the same programming as it was received and may not operate in the truck.
If you intend to send HP Tuners an E41 ECM from a different truck, this is NOT the right service option for you—please select the EXCHANGE service instead and read the description.
HP Tuners is not responsible for mistaken Upgrade/Exchange service options. Please read the descriptions of each service option carefully before checking out.
