I just added BBK Long Tube Headers, Bassani Catted X-pipe and SLP Loudmouth I Exhaust. I also have JLT Performance Ram Air Intake. I am currently running the Diablosport tune. What settings should I place for Best Fuel Mileage during the week and Best Performance for the weekends. Thanks guys!

Your best bet is to get a custom tune for the mods you have. We can handle that for you or you can find the nearest tuner that has a dyno.

I have a question can this tuner on this same car work with a custom tune if putting a super charger on?

[GP-SE]

yes if you add a supercharger you can have a company tune the car, then make a custom tune for your supercharger setup that can be uploaded to the car using your Predator.

Thanks, so it is possible for the U7146 to have a custom tune to use on this car with a supercharger? Just wondering because it says in the instruction manual it does not work with supercharger but figured that meant with the stock tunes not a custom?

correct... you would have to get a custom tune made for that setup by a diablo CMR tuner... then load it to the predator and install to the car...
