Well, can you do it as simply as that when not only are there new injectors, but new intake manifold, new (427) engine, larger turbo housings on the STS turbos, and a new fuel system?

I'm just trying to figure out the current tune on my car and figure double checking what is there against what seems like SHOULD be there is a good way to try to figure this stuff out. The IFR table has to be wrong (it's a diagonal line instead of a flat line) with the mapped fuel pressure regulator I am using, or I am seriously confused about how that is supposed to work. So I would like to try to figure out what it SHOULD be.

I know my join date makes it look like I've been around here for a while, but such just is not the case. I registered when I purchased my copy of EFILive, and haven't touched it until just a week or three ago. So I'm a very raw newbie at this stuff. So right now I'm reading the hell out of this forum. And not planning to flash anything until I've got a good idea of what I am doing. Otherwise I would surely just make things worse. Not that the car is running bad now, but there does appear to be some rough edges that need to be taken care of.

Thanks.
