so at this point...if i have the walbro put in already...is there any advantage to having an AFPR installed...even tho my car is already tuned??

Yes... by having the walbro in the tank and using the stock FPR it tends to bump your fuel pressure out of spec, using a SAFC to try to correct that jump is a little much. Your suppose to use a SAFC or similar to "fine tune" your system, not compensate for big jumps.

Your best bet would be to get a AFPR set your base and then tune from there, a knock monitor or a wideband would also be a good investment.

If you live in a controlled atmosphere, and never chance a single thing related to the engine again, then you'll be fine for the most part.

Your biggest issue will probably be finding any sort of consistency over a long term period, since your car has basically no control over fuel pressure any more the ECUs learned value will be constantly changing to compensate for varying scenarios/conditions and your open loop AFR reading will change with it.
