Tuning A 20g w/ An AFC

[CYrUs0k5]

I have a Slow Boy Racing 20g turbo... front mount, all other basic mods ported manifold, o2, downpipe etc...

I am getting an AFC this week, version 2. Need some "base" tuning levels. 550 injectors and a walbro 255 fuel pump... Looking to start on 12 PSI

What PSI do you guys recommend for pump gas.... 18? Will this blow out my spark?


THANKS

What's your fuel pressure set at?
IMO,
550's; low -10% across/high -8% across

i say get a logger, then start at zero and keep changing it based on knock, and timing. Also you may want to get bpr7es, or 8's. When running higher boost those 550s may not be enough. Boost though safe on a cold night is 18 or so pump with a good tune but 20gs can handle more then that on pump.

You should be fine with 20psi on pump if the Injectors can handle it.

You need a logger so you can watch your Fuel trims.

Start the SAFC at around -15 On the high settings on 94octane gas and 16-17 psi and you should be fine..
