Hey, I have a 355, ported upper plenum, accel lower, slp runners, edelbrock headers, flowmaster exhaust, holly regulator, 22lb injectors, hmm... the rest is pretty much stock. What would be the best fuel pressure to set my car at? Your help would be greatly appreciated!
Also where can I get a prom that doesn't have the Cold Start injector setting, or an 89' prom without vats?


Thankyou in advance!!!!!!

 

Best fuel pressure is going to be specific to your vehicle, you're going to have to run a few pulls while trying different pressures untill you find your best setting for performance and economy.


You'll end up between 40-50psi (or should)
