You won't have all that boost to compensate for anymore, so you'll run super rich. That being said, my friend had only a high flow inline fuel pump, colder spark plugs, aftermarket ignition, and a nitrous controller...and he ran 125 shot on a stock GSR motor. All it takes is proper tuning. Now I know people are going to come on here and say it can't be done, but it CAN, and it has. Now that's not to say that you won't run into problems. Whenever you're running that much nitrous/boost, it doesn't take a big problem to say bye bye to a motor. I like to use this phrase when it comes to these things....You play, you pay.
something I am not COMPLETELY sure about is how the VAFC HACK works.. I mean, if I tune the injectors down to stock (-45%), all the way through the power band, how would I be running rich? Cuz technically, it is still reducing the flow of the injectors enough to make it near stock..... But I am not sure.. Just my opinion.
