36lb or 42lb injectors

[joeyd0730]

hey all, happy holidays. i need some input. i currently have 30lb injectors on my blown 306. S-trim so 14 psi max pds of boost . producing very close to 500bhp. fmu is currently at 6:1. i have a 190 in tank with a t-rex. should i got to 36 lb injectors or 42's? i have the plates to recalibrate the fmu to 3:1 + 4:1. thanks for advice.
to many mods to list, you can basically see my mods in the pic to get a idea. thanks joe

Is it running out of fuel on the top - you have a/f ratio data from a wide band?

42's!! and ditch the fmu!!!

12.5:1
i was thinking that as well. my inline regulator has a 1:1 refrence

Get the 42's and get rid of the FMU.

42 for sure. I would try to get the A/F down to 12:1. It never hurts to be a tad rich. The 1:1 regulator is not a bad idea.
