Besides peoples point of views on putting back your car back to stock, the biggest upside to the current ECU Tune vs Piggyback is ease of removal for me. I am working on getting my rotors replaced under warranty and with my JB4 it takes me 10 min to pop on and off to go back and forth to the dealers (4 times so far). With an ECU tune i would have to NDA the ECU to you and have you NDA it back everytime i need to go in. That is not feasible for me as this is my daily driver. While I would love an proper ECU tune its just not worth the risks for me at the moment. I understand they can be safer options, I understand Dealers cant technically void your warranty... but they will. I for one dont have the time or pocket lawyer to help me fight it.
For now its Piggybacks > ECU tune for that reason. Also, the similarities in HP, TQ, 1/4 times, Boost PSI etc for a quarter of the cost if not more is also very attractive.
When we have the ability to flash updates/custom maps and stock software at home then ECU tunes may take the edge for me, but until then I just cant see the real upside of $400-500 vs $1,800+ (spare ECU included in that price).
I do think there shouldn't be any additional upcharges for going for Stage 0 to 1 to 1.5 swell. Once you pay for a tune you should be able to get what ever flashed maps you have developed similar to piggybacks.
Again, I do hope I can get a proper ECU tune one day as I do see the benefits but at the moment I just cant see the real upside vs cost, risk taken, and ease of removal to stock.
Tork is doing great things and in time im sure they will have everything figured out and give us what we want. I will be a customer at that time!
