What is the horsepower limit on a set of stock 32lb injectors on my 2005 VIN-Z L59 on 93 Octane... I guess what i'm asking is can i run my 5.3 single front mount at about 7 or 8psi and be ok if i upgrade to the 255lph walbro? Or do i STILL need the 42's?
My money would be on that the FF injectors will not be enough. You do not wanna run short of fuel on a FI motor...or any motor for that reason. Detonation is not good. Go ahead and get 42lbs at least. 8.1L Marine injectors (44 lb/hr) are 100% plug and play.
Id go ahead and spend the money on some 60lb injectors. Ull want more boost later on.
Buy bigger and sell me your FFs.
