im new to this platform and want to make sure my car has enough fuel. right now i have a catless test pipe, bov, cobb intake, and cobb accessport stage 1 sf 91. at what point do i need to upgrade the fuel pump and injectors? i plan on getting a TBE and running stage 2. let me know. thanks.

 

Turbo upgrade, cam upgrade or if you plan on running E85. stock injectors and pump seem to be good with basic bolt ons and tune. Just keep an eye out on the Fuel pump relay.
