If it starts to run lean you can buy fuel rails, an external regulator and boost the fuel pressure up a little bit. The stock pump will put out a little more pressure. Are the injectors 40 pounds at 43 lbs or 58 lbs of fuel pressure? They should be fine considering how small the injectors are in the 6.0s, 5.7s and 5.3s.

hey i hate to jump in.

Red,
are the ls1&#39;s (f bodies) fuel pressure different from us trucks?
if so what are they?
the reason why i&#39;m asking is b/c i&#39;m doing the ls6 intake swap along with car style injectors that are factory rated at 28.8#&#39;s
i know i have to change the IFR table but just wondering if the fuel pressure between the cars and trucks are different.

thanks in advance,
