Sooooooo, long story short........ do I have to start from a factory tune before installing ANY of the Predator tunes? Meaning, with an 87 tune installed can a 93 be installed over it? Then can I go back to the 87 tune without reinstalling factory tune first? According to the "last tune installed" menu....... it said it had the "Diablo Tune" in in. If I am not mistaken, the 87 tune is called the "Diablo Sport Tune". Look forward to hearing back.
On another note, the change is incredible with this 496 cubic inch monster. A weeeeee bit of brake torquing to break the tires loose, then stay in the throttle
Wooooooooooooow, the tuner really wakes up the sleeping giant of an engine. It will now smoke tires all the way through 3rd gear! Of course, this isn't my normal driving style. Just had to "play" a little. Very pleased. Wish you guys made/offered decals......... I need to advertise. Well, then again......... maybe not, don't want everyone knowing what the truck is cabable of
