well bad news on those they were not the right ones...but he thinks he can get me a pretty hefty discount on some 60's later if I want. Since im already making 16lbs do you think I need swap the pulleys?
I usually see 16-16.5 psi depending on what gear and temp. If you're getting the injectors for free then by all means put them on as long as they are the correct ones and are flow tested.
Prochamber is just a midpipe like your Bassani X-pipe. You're going to have to spin that blower harder if you want to make good power. Either switch that 3.1 upper to a 2.80 or switch the 4lb lower for an 8lb.
