Sounds like you are headed in the right direction with your mods. Before I did any tweaking I would put the car on a wideband/dyno and see what the actual AF ratio is. Then make a determination as to weather or not your assumption is correct. This is certianly cheaper than a good AF controller if it turns out to be running right, and will also tell you how far you have to go with it.
The SAFC is something a lot of people use and it appears to work pretty good, although if it is only marginally off then perhaps an AFPR might be enough adjustment to lean it out a bit. Again knowing where it actually is on an accurate wideband would tell you what the best route is.
