The 2G MAS is not a good match for the stock 450cc injectors on a 1G. If you are going to run a 2G MAS untuned on a 1G then get 550cc injectors (or something close such as those EVO injectors).

Although harsh, here is the best advice you'll be given all day: Cut the bullshit and trying to be a cheap-ass and mod your car right. If you can't afford to do it right then don't do it at all; you'll only end up costing yourself more in the end and run the risk of destroying your car in the meantime.
