Diablo Predator tuner

[HeMiBoB]

I have one of these tuners, just wondering what works best and what kind of gains can be expected. Car has cat back exh system, cold air kit, not sure if any other actual engine mods is present.
The car has other non engine upgrades however, 4.10 gear etc.
I know this thing can do a bunch of stuff but was just going to install the basic Diablo Tune, without modifying any other parameters etc.
Thanks
Bob
car is a 99 Mustang 5 speed GT BTW

Yea, I would just install the diablo tune as it is. With your mods, you don't stand to gain much of anything by tweaking it any.
