I have a set of RC Engineering 550's I'd like to go ahead and install, but I can't find which combo to use. I found a couple posts of people running them with the SFMU but no info on the discs they used or what psi to set them at. I do have a SAFC to lean them out if needed.

Hahn Stg 2/SFMU 8psi(going up to 10psi once I finish the Greddy boost controller wiring)which I'm well aware is a risk on stock internals lol. Also installing a ported/bored IM/ MP 60mm tb and high flow fuel rail. The MS and Aero 1:1 will go in sometime next month(need to order more fittings)
