At what point do you need fuel system upgrades??

I want to just run a 2.8 or 2.93 pulley and a good tune with the other usual stuff like exhaust, intake, idler etc I should be ok with the stock fuel system right??

You should have no problem with that setup.

yup. you might be close to pegging your maf, and you wont have any headroom left in the fuel system for much beyond that, but the mods you listed should be ok.

with only a 2.93 upper, jlt true cold air, and stinger cat back, im >90% fuel pump duty cycle, and was too close for comfort regarding the pegging of the maf sensor.
