my recommendation, get it done by a pro. on the dyno hooked up to a computer, they'll get everything you can out of it, and safely.

if you load the predator performance tune in it will modify most of the settings for you to get the most gains. You will notice a difference.

Premium Fuel

The canned tune in the Tuner requires Premium Fuel. Be sure you have the tank full of the good stuff before installing the tune.

To do a full custom tune requires 2 things: A tool to modify the computer and the exisitng tune (you have that in the handheld tuner) and a method of monitoring and tracking the air/fuel flowing through the motor (the best method would be via a Wideband O2 rig such as is sold by Innovate).

The Diablo is a very handy tool, but its trying to work in total darkness without the feedback loop from a well-equiped dyno setup or the Wideband O2 rig I mentioned. It CAN move spark advance and air/fuel mix where you want them, but you don't KNOW where you want them without the data from the dyno / O2 sensors.

I would recommend you try the canned tune and use the tool to adjust for rear gears, wheel/tire size changes, rev limit, speed limit, OBD II trouble codes, auto tranny shift points and firmness, data logging, and so forth.
