I just got a GS and I am in the works of boosting it. But I do have a problem I was wondering what you guys run in terms of an FMU what ratio do I use? I have stock internals and a Garrett TBO363 turbo if that helps. Thanks for your reply.

It depends on what boost level you want to run, and what injectors you have. I have never heard of that turbo before, either.
In any case, if you are running 7-8psi on stock injectors, you can just use a 12:1 rising rate FMU, get a Vortech one if you can... they are very cheap. Otherwise, get the Vortech SFMU since that gives you a lot of tuning capability that is missing from the regular fixed rate Vortech FMUs.
