If you do a turbo xs unichip fuel cut is raised to around 21psi. I dont believe cobb and vishnu use fuel cut built in there systems. You could get away vf-28 or 29 without injecters or even a FP turbo would be good. A larger fuel pump and pluggs would be needed at ant turbo up grade. Get some gauges also. You cpuld also do a fuel controller but it does not control timing like the unichip. If you go vf-30 on up injectors, pump and pluggs are needed.

If you don't get the pump and injectors, you could run very low boost. Ideally you want at least injectors and fuel pump for the fuel side and an intercooler.

UNIchip is not a brand...it is a part. It is a chip that works with the stock ECU (computer). It is considered plug and play because you more or less just plug it in, and it starts functioning with the car. Vishnu, TurboXS, COBB....they all offer one. There may be more, but that is all that I can pull off the top of my head. The chip will control timing, boost, and air/fuel ratio.
If you don't want a unichip, you can replace the stock computer with a standalone unit such as a link. This is costly and hard to manage/tune....unless you know what you are doing and are quite good at it. No offense, but if you are asking a question such as the one found in this post, stay away from this route. (at least for now) It would be fairly easy to cause some major damage to your car.
A third route would be to buy air/fuel controllers, boost controllers, timing controllers, etc. and have about a half dozen mini-computers in your car. This would work, but I am pretty sure it would be a HUGE pain in the ass for someone that is not very skilled at tuning.
You asked how to remove boost cut: There is a product called a "boost-cut defender" that will do it for you. I beleive MRT makes it, but I am very unsure. Look it up.
You say you need a bigger intercooler....I would say that the injectors and pump are more important the intercooler, but
An entire encyclopedia's worth of information could be written to answer just the simple questions you asked. Most everything that could be discussed about our cars and mods, has been discussed (most likely twice ). Try running a search and you should be able to find more information that you would ever want. If you still have questions after reading through the old posts, then ask some questions.
Grant - hopes this helps
PS gauges are very important, but they are not going to do any good unless you know how to read them and what the acceptable parameters are.
