Try and hook up a gauge and see what % your fuel system is running at WOT. In most cases, people with a bunch of bolt ons AND a cam need bigger injectors...Quote:

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
Run some 8.1L injectors.

42-60s will be a bit excessive for an N/A, cam only 4.8-6.0
I'm running 42s in my bone stock 5.7L without any issues though they do honestly belong with my 408.
ok well i think ill try to grab some from an 8.1 then...thanks for all the help :thumb:
