Individual Custom Tune File

Do you have an HP Tuners MPVI4 or RTD+ with credits but just need a tune? We have you covered! Take the guesswork out of it and let one of our specialists with over 20 years of combined OEM experience develop a custom tune to fit your needs. Simply supply us with your stock .hpt tune read upon checkout and we will turn around a tune for you generally within 3 business days. Extensive mods or lack of technical information like injector model data will take longer. This is for 1 tune file only. Each additional tune file is a separate purchase. ECU Unlock sold separately.  Your ECU must be sent to us for unlock first if it is not already unlocked with HP Tuners.
