EZ LYNK Limited to Full Support Upgrade

Upgrade your EZ LYNK from limited support to full support. This can be purchased anytime before or after your limited support expires.

Please send your truck's VIN number along with your order number to support@4jtuning.com for tune processing.

We will always try to get your tuning package completed as soon as possible, but just in case, please allow a day or two for processing.
