Do I need to upgrade fuel pump/injectors?

[toennee]

So about 5 months ago I bought an 08 GT500 from a dealer out of state so they were unable to provide a lot of info on the car. What I can tell you is it came with 2.6 upper, BBK longtubes, offroad x pipe, Magnaflo axle back, JLT intake, and a custom tune. I have purchased, 15% lower, 13/14 heat exchanger, 3x coolant tank, and ported m122. I am undecided but if I can find a deal on a 65mm TB I may also add that. Will I need to or would there be any advantage to upgrading to bigger injectors and fuel pumps?

Thanks

No, you should be fine. With that 15% lower and stock upper pulley your probanly at 11lbs if boost. The port job just makes the SC more efficient and will help the engine pull less timing.

Thanks.... It does also have a 2.6 upper if that make much difference.

If youre fortunate to have 93 octane as your premium fuel, you should be fine with that pulley combo. For those of us out west with shit 91... that combo would cause some issues lol

We are lucky and have 93 everywhere. And there are a few places with 100 and 110.
