One vehicle at a time

This is an awesome product. Installed right away and had a very noticeable difference just on my stock 6.2l gmc. I don't have anything modified yet but this still gave it bigger balls. The only bad part is even with the expensive price, you can only install on one vehicle at a time. You have to restore factory tune on last vehicle before new vehicle is set

So I bought this tuner not knowing anything bout it. I was worried I might not know how to properly install tunes and mesure paeameters. Well after a while of research I found out how to installl tunes I tried the 87 octane tune. Right away I felt a huge difference my truck was awake my acceleration was different more responsive. So then I did more reseach found a guy by the name of lew or diablew tunes predator gives u the option to install custom tunes and gives u the information you need to find people that can make a custom tune for ur car/truck. I found lew won't go into much detail but he tuned my truck with balls. There is so much thing u can do with this tuner if u have mods on ur truck a custom tune is for you. Or even stock vehicles can enjoy this great product.
