Do you have a FMIC? For a pump I would just go with a Walbro 255HP.
Not real sure how well the MAF-T and SAFC II would be for tuning, probably not ideal, that's for sure. I would go with a $10 chip from Shane with a custom dyno tune on it. Getting dyno tuned is the only way to go, especially if you're not real sure at what you're doing when it comes to street tuning. That way you could sell the MAF-T/SAFC to help pay for the tune.
