Why not go Crome? Or at least E-manage/Apexi AFC/AEM FIC?

avoid fmu's all together...horrid ....

do a good mild tune. pm zeeman, what he costs for a solid ecu tune costs crap all...esp in the long run....

If you havent bought a FMU dont, just get an obd1 ecu and chip it and convert to obd1

Post your setup and people will have a better idea of how to help you as well!

definately don't waste your money on a FMU. Pushing 100psi through stock injectors (or any injectors for that matter) isn't safe.
Think about it, the stock fuel pressure is 50psi (roughly). If you're using a 10:1 disk (which is pretty standard for a FMU) that would be 10psi of fuel pressure for every 1psi of boost. So at 5 psi of boost you'd be running an additional 50psi of fuel pressure on top of the already 50psi of fuel pressure the stock regulator will maintain. So thats 100psi of fuel pressure at 5psi of boost. Pretty crazy eh?
Now, to have 100psi of fuel pressure with no sort of timing retard is just plain ludacris and is FAR from what i would considered getting your car "tuned".

Don't use an fmu...

Unless it's a beater like my turbo cavalier was and don't care if it blows up......
