No, no big sigs here. They are pointless because in the future if someone searches for "GSC 272/264 cams" everyone of your posts will come up. That would suck and lead the person though wading through a lot of BS... Not that your posts are BS... You know what I mean.
Anyways, you're better off with something suited specifically for your set up, and your right, something "just over the counter" isn't going to be optimal. Out of the two that you've mentioned, ECUflash sounds like the better option to me. Yea you'll have to buy the laptop, but the control over fuel and timing it provides will be better than the piggybacks. Plus you'll have it and the cable for logging which is crucial for monitoring your fuel and timing changes. MAFTpro will work, so will an AFC, they are easier, but if your going to be really pushing the boost (which I assume is why your getting alky too) your going to need more control they just don't provide.
Get the laptop and cable now. Practice on what you've got and start taking "baby steps." Make small adjustments and see and learn what those changes do. Lean to look for dangerous situations and what works best for your car. Once you've got that down and some experience, it will be easier to step to the next level.
