Ok i am in the middle of getting my 42 lbs injectors finally and want to know some good opinions on the max boost i should run on pump gas? what about race gas? I have everything in my signature minus the injectors that will be going on by next weekend. is 7-8lbs the max the injectors/motor can handle on pump gas?
stick with 5-6lbs?

first off are you running an intercooled or non-intercooled setup. that will make a huge difference on a safe boost limit

non intercooled should NOT go above 7psi
intercooled should be safe at 8-10 maxx
i hope you have good headgaskets and head studs!

ok then i will stay under 7 till i get an intercooler or meth setup. my main concern was the fuel limit with 42lbs injectors and a 255 pump
