cat back prep and a product q

[tyler]

Hey guys just got a call from the muffler shop and they said my 3inch catback is ready for fitment. And after a few weeks of working 14hour days I finally have the $$ to start some upgrades. My car is a 90 gtu with the tii swap and only has a cold air intake so far. I know with the soon to be catback there will be some boost issues and as soon as the car gets back its going to sit for a week or so, that way I can finish my fiberglass project. While it sits I'm going to have the wastegate ported and install a fcd and mbc. Will that set up be safe untill I can afford to get a safc to tune it better?. Also what's better, the afc- neo r the safc 2, I've read mixed results about each?
