More power!!!

I have a 93 rt tt with 3 inch downpipe and exhaust, k\n filter, and a mbc set 14 psi. The car feels great but i was wondering if I could install 550 injectors without flooding the engine, or will i have to get an safc to tune it. Also, how much of an improvement would the 550's make. I also had a question about installing an egt, where would I tap the probe for the egt? Any help would be appreciated thanks!!

You need a fuel controller for anything but stock injectors. The EGT probe would go in either of the manifolds.

this is how i see it... the only reason you put bigger injectors in you car is because you get bigger turbos. whats the point in buying 550cc injectors and then get a SAFC to reduce the output of the injectors. kinda pointless yes? so really no gain. there.

^ agreed, alot of the modifications you can do to a turbo'd car are those which yield greater PSI, i.e. you can either up the boost on your current turbo, or upgrade to a bigger one.
