Hello. New to the forum. Purchased an 06 Gt last year. Have put msd coils and underdrive pulleys on. I have a tuner also. Just purchased a ford racing intake and 63mm throttle body. Will I need bigger injectors to handle the increased air flow. The engine is stock. Just the add ons. Thanks for any help!!

No, you won't need increased fuel for your mods. When you get closer to 425-450 at the flywheel, then you may consider bigger injectors as it may bottleneck your power. Also, for your mods, the higher air flow won't really impact your power. The tune is where most of the power comes from. Again, when you reach closer to 425-450 the intake system becomes a bottleneck.

 

Thanks for the advice. Dont want to put money where I dont need it. Think the next update will be cams.

 

The stock 24lb/hr injectors are good up to about 370rwhp (420hp crank) and you're nowhere near that.
I really think you should wait until you have performance cams and then install everything at the same time. Then you can get a custom tune from Lito. Since you'll still have the stock valve springs, I suggest you set the rev limiter at 6700rpm.
If you don't already have long tube headers, maybe you should get those too and install them at the same time as the other parts. It'll be a better matched combination and you'll enjoy the results.
You'll inevitably lose some torque at lower rpm and feel the need to do a higher ratio axle gear swap but since your stock gears are 3.55 rather than 3.31 ('07-'09 GT), you can wait and see how the car feels before you decide.
