06MonteSS thanx for the replay but do i have to adjust the fueling because i have no idea on how to adjust properly and change the settings of the predator im no expert..

C6 Z06 with K&N filter and B&B Exhaust system... does it need a custom tune to get max power??

yes go for it just bought one today and ul notice the difference.

Well my car has small bolt ons so i guess i would get more hp with a custom tune but the problem is that cant find any dealer near by

Bought the predator and installed the tune it worked fine but i didnt get the octane choosing msg where i choose which octane im running?? how do i get to choose it??

thanx

Is it possible to get a Custom Tune online like sending the diablo file to the tuner and listing the mods of my car and the new tuned version is send back to me by email??

Any good Diablo Tuners out there??

Im thinking of Buying a Used predator U7194 from a friend and he says that it didnt work on his car because its a early production Z06, but he said that he only used it two times for clearing codes and erase faults because of his exhaust system and data logging..

So do u think its ok to buy it?
