Hey guys I am currently swapping a 1jz into my 240sx. Will an SAFC or NEO tune be safe to run with jdm 440cc injectors and my sc61 on wastegate boost at 14psi. This setup usually dynos around 350whp. I will do the tuning on a dyno along with my AEM w/b to verify A/F ratios. My concern is will my stock ECU advance the timing too much with the SAFC correcting for the 440's?
