So I'm looking into tunes and tuning softwares and have a buddy who just ordered HP Tuners. Every Lightning I've seen has been tuned by SCT X_ tuners and i was wondering why that is. Basically you've got 600 some odd dollars for a tuner and tune but you can only use it with one vehicle at a time, so if you had say 5 Ford vehicles, and you wanted to tune them all, it would cost roughly (5 vehicles x 600 dollars) = 3000 bucks. However, if I'm understanding correctly, HP Tuners costs roughly 600 bucks to buy the pro version and the tuning credits are about 100 bucks to buy ($50 x 2 credits per vehicle avg). When you buy the pro version, it comes with 8 tuning credits (roughly enough for four vehicles at 2 credits per vehicle avg). Therefore the total software cost of tuning 5 Ford vehicles would be roughly 700 dollars as opposed to 3000. Am I missing something here? Why would anybody use the SCT stuff? Thanks for the help in advance.
