yea as u said i have no tuning experience

and my supra is my daily driver so im going to take ur word for it and go lex afm/550cc. So i can safely do the lexus/550cc upgrade with out any sort of fuel management right? Simply because +25% air +25% fuel = happy engine? I think id rather just go stock afm, 550cc and fuel regulator. Im not trying to be crazy with it, it is my daily driver after all lol But a solid 14-15psi of boost seems nice. But as in fuel regulartor, does a safc count or is this a totally different system?

Yes, the SAFC, SAFC II and NEO are three of the most common fuel controllers. If you have one already you don't really need the Lex AFM unless you've already got one handy. As I mentioned, some people found some tweaking was needed to get the car running smoothly but this can be accomplished by manipulating the physical hardware if you don't have a fuel controller. Also, as previously stated, a baseline dyno will let you know if you're running too rich or lean at WOT and they should be more than happy to tell you what your car is idling at.
