I have a 99 Cobra with a newly built motor and I don't intend on adding a power adder(NOS, Supercharger), the engine is bored .020 over with Forged Probe Pistons and Manley H Beam Rods, everything else(fuel system, intake etc..) is stock except a Densecharger cold air kit,off road H pipe and Catback kit.
Question will the 93 octane tune in the U7146 Predator be sufficient to get the most out of my computer or would a Dynotune from a DiabloSport dealer that has the correct software get me more HP? I'm aware that a custom tune can be downloaded into the Predator then transfered to the car? I see the tuner gives you the ability to see and adjust the Air fuel ratio in real time, so if I see the range at 11.5-12 would there be a need to shell out $200 for dyno runs if the gain is very little?
Also does anyone now if you can download a tune specific for the 32V Cobra motor from Diablosport since the U7146 covers a range of Mustangs, Thanks CJ

hey there.. I think most would would agree that every car tends to be different. Depending on barametric pressure, air temp, and so forth. Even two identical cars with the same build date have the potential to throw out two very diff dyno numbers. Sure the plug n go tunes are very user friendly but will not account for a few small details said above in your genneral area. If u can find yourselfe a respectable tuner, they'll be able to get the most bang for the buck out of all your bolt ons you spent all that time and money on.
