Does anyone on this board have one of these? I was wondering how this thing works before I get my kit. I'm assuming it's like an AFC, but is this thing hard to tune? If any of you guys have heard anything about this thing, let me know. Thanks....

I dont believe you have any programming to do with the powerfuel module. Also, your signature says HRC stage 4. The powerfuel moudule is only on stage 3. You'll get a DFI with the stage 4 :)

Thanks for the help SaberKahn....As far as the sig goes, I did that up awhile ago and since then have changed my mind(too much $$ for my budget). I've just been too lazy to change it! Oh well.....

the hrc powerfuel module for the stage 3 is already programmed for that fuel setup! as far as i know from bill its still in the works for perfection. stage 4 and up is a programmable kind...
the powerfuel module is like the super afc but its able to lean or control the 550cc injectors unlike the super with the 550cc which runs the car super rich correct guys?

You would definitely run rich at idle with 550s, even with an S-AFC.

the HRC stage III comes with 500cc injectors, not 550cc...correct? at least that's what their website says.

even with 500cc it will run rich, anyways bill is always changing it around from time to time

Greg has the 550cc injectors with the safc and his idles and runs fine. Being a tad rich can be a good thing.

Rich = less power, but also less detonation. Running a tad rich is a very good thing if it's a daily driver in my book. Just have to clean the injectors a tad more often, and maybe a new cat a couple thousand earlier.
