I just installed and have some ?

[Ryanhnt]

I just installed my U7145 on my 07 Mustang GT, I all ready had a Airaid CAI and when I installed it about eight months ago the exhaust note and the power was there instantly. I kept my venturi tube in and just installed the stock 91 octain performance tune and took the car out for a drive. I have not noticed the kind of gains I experienced with the CAI, and would like to know what I can realy expect from the tune? Or is there something I'm not doing?

I am running the same setup on my 07 GT. You need to remove the venturi tube and tune to the 91 Octane Airaid tune in the Predator. Since I am running 93 Octane I also bumped the Gobal timing 2 degrees to compensate for the higher octane. When I kick it it really goes. You can tell the tube being gone is allowing one heck of an airflow. It not only goes but fuel mileage has increased. I also installed the Ford Racing mufflers that come on the Shelby 350's and it sounds great. Not to loud but like the old Mustangs from the factory. I had a 69 mach 1 and this car is like the Mach 1 reborn except it is faster, handles better, and built better.

Try doing as 69mach suggested. The AirRaid tune with the venturi removed will give you some more hp.
