I am a member of turbod16.com and I am familiar with what kind of tune to run on a D16, but now I am getting into a different world with a B16. I donâ€™t know what would be a proper tune a stock b16 in a 89 ef si. I will be running a Garrett t3 42/48, DSM 450 injectors, FMIC, walbro 255 fuel pump, log manifold. I would like to be in the low 12's in the 1/4 mile, I have seen videos of stock b16's running high 11's to low 12's with only 10psi, that is unheard of with a d series so I am pumped! Is it ok to run a AFC hack on a b series with about 10psi, or is that unreliable. I know that with a D series you donâ€™t want to go above ~9psi that yields around 200 WHP. So I have no idea what applies for a B series and if you would even recommend the AFC hack, thank for your help. Plus do you guys know of a good site that I can get piping for a FMIC for my 89 ef si, thanks.
