would it be recommended to upgrade my fuel injectors with my new cam swap. I just put in an ls1 hotcam and i was just looking for some input. next im looking on getting a new tuner from nelson and tc in the near future. btw its a 99 5.3 silverado. Thanks

Try and hook up a gauge and see what % your fuel system is running at WOT.

i have a cam, intake, headers, tune, and a heavy foot
me and virgil hooked up my truck to his HP tuners and it said i was running at 98% fuel capacity for teh injectors.... so im bumping mine up to 30# injectors.... soem people go bigger to a 42# and 60# for outrgeuos stuff....
i would say a 30 or 42 should do you well in the long run

'99s have the smaller injectors. You'll max them out quick with a cam

42-60s will be a bit excessive for an N/A, cam only 4.8-6.0
