www.TurboEdit.org

Not to be an ***, but I think you have a few things confused. The FMU doesn't advance your ignition. It just raises the fuel pressure to a dangerous level and puts a large strain on the injectors and fuel pump. You have no tuning options with it. You just slap it on and hope for the best. That's gay.

If you install larger injectors, you need something to control them with because the stock ECU will not compensate for larger injectors by itself.

Running TurboEdit with 450cc DSM injectors will run you a couple hundred bucks and you will have superior tuning capability along with a nice power gain over an FMU or AFC alone.

Boost doesn't advance your timing. Crappy piggy back systems advance your timing. It's also safer to run less timing on F/I applications.

For only 8psi, I might use an FMU, but no more than 8psi. If you're not looking to break any hp records than just stick with the FMU and call it a day. If/when you get serious you can upgrade to a real fuel management system.
