rtek vs. safc
Can someone enlighten me on the differences?
Also, I'm planning to run 10-12psi. Not too much is changed from stock except for the cleared up exhaust and assorted reliability type mods. Which would be better for my setup? Or is there even a need for either one?

Nurse I need 1300cc's NOW
i am getting both . but i would get the R-tek first because it retards timing, takes out the fuel cut, amongst other stuff. it even says on the website i believe that if you get the r-tek you dont need to trick your safc to run bigger injectors. but i would think that they would work well together hand in hand

this isn't really a vs. type thing rtek 1.5 or 1.7 and safc are two completely different things.
rtek alows you to not need a fcd, if you want to run 720's on a stock engine you can go 1.7.
If you want to get something right now unless you have the 720's go rtek 1.5. both rteks from what i've read only allow for minor modifications.
If you want to try to tune your vehicle go safc.
In my own opinion I'd go one of the rtek and then on to a feul managment system (probably emanage) unless rtek 2.0 comes out soon.
by the way if you do go rtek 1.5 you can always upgrade to 1.7 for a little more later. (not sure how much, haven't been to the site lately)

A) It comes untuned from the factory, and a professional tunes it to match your particular engine's requirements or
B) You tune it to match your particular engine's requirements, and hopefully you know what you are doing.
Rtek is a reprogrammed ECU (aka "chip"):
A professional pre-tunes it to paramaters that generally match a certain engine configuration. There is no chance for you to screw it up, or for a professional to make it better match your particular engine.
The two concepts are totally different.

Main idea:
The S-AFC does what you tell it (within its parameters). The Rtek does what somebody else told it.
Fine points:
The S-AFC and Rtek chip do not change the same parameters of the stock ECU. The S-AFC can do some things that the Rtek can't, and the Rtek can do some things the S-AFC can't. You can read the list of their functions on their websites:

You can't compare the S-AFC and Rtek chip. From a fuelling perspective, the S-AFC allows to to tune the fuel mixtures across the rev range, whereas all the Rtek does is allow you to run 720cc/min secondary injectors (in fact you have to run those injectors or your engine will lean out and blow up). If you get an Rtek chip (which isn't a bad idea) you still need a fuel controller if you want to tune the mixtures to suit your other mods and/or lean out the stock rick mixtures for more power and less fuel consumption.
