Custom Predator Tune

[StalkerStangGT]

what kind of custom tunes have u guys made with ur predator, i have the stock tune as far as power goes.....im kinda nervous to fool with the timing and a/f ratio cuz i dont know enough about it........ i would like to squeeze all i can out of it though safely

my new predator is on the way. but the article in here that used it on a dyno said leave the a/f where it is because the predator tune is as good as it gets but max out the timing. maybe to be safe bump up the timing a little at a time and listen for pinging.

I think you can get more power if you run your engine cooler. I know my car feels faster before it warms up, but there is more engine ware at cooler tempretures so there is a price. I am going to try experimenting with it more though.

Well I got a quick response from diablo so here it is. I asked what the normal operating temp was with a 180 T-stat and if going colder would help.
Most engine temp for eficintsy is around 188-193 so you are
doing good, anything colder you are wasting energy, and the fan are
exact to temp adjustment

Most people can max out their timing advance and not get any pinging at WOT. Try it out. If it pings at WOT, back it off a bit. Keep in mind this does not affect part throttle. If it pings at part throttle, it's your gas.

Next step would be to get a dyno run with a/f readings and tweak your a/f ratio to 12.8:1. You'll get the most out of your Predator with those two items. Auto guys get a bit more by firming up the shifts.
