I dont know about a stand alone unit, but look into intense and see if they can fix you up with something. By the way (kinda off topic) what kind of plugs are you running with the 2.79 pulley???

i'll answer a few things here...

first a SAFC or something along the line of an air fuel controller and/or a stand alone as of yet are not needed.

our ecm will support up to 64.75lb/hr injectors, and if you manipulate your VE table, commanded AFR's, and your power enrichment rates you can accomplish any AFR at any RPM you want.

HPTuners FTW!

HP Tuners is bad ass, except for the fact that you must purchase credits to use it. That is why a stand alone is better for your everyday tuner w/ basic tuning knowledge. Also w/ a safc2 you can personaly tune after adding a mod. With HP it's harder to tune as often due to having to purchase credits, wich sucks ass. I would only use HP once I was done modding my car and was ready for a full and final tune.
