Many people are going to tell you that the whole idea of a computer is the Fuel Management. Its is not so much a problem with boost, although I would get the controller, but a problem with enrichment, and leaning out.

yea i know but isnt the computer for enrichening it when ur boosting

Only way to tell is if you dyno your car and see what your a/f ratio is. Every car is different, as long as you keep your boost at 10psi, it's going to be hard to keep boost steady with a midpipe. You can increase your pressure by 10 psi and it should give a little more fuel. Once again, each car is different so dyno it.

When you say full exhaust, do you mean a dp and mp? If so, your asking for trouble even if you get a boost controller. Get a power fc and you won't have to worry.

well yeah it's for enrichment when your boosting, and all the mods you listed are for boosting. I think you could maybe get by if you put it on a dyno and had it tuned really rich, but one little boost spike and....

Thats my point, so why risk it? Especially if one doesn't have $2000 for an engine sitting by and another $1000 for the install if ya can't do it yourself.

The real question is can you control boost? You may need to port your wastegate to do so.

IF you can keep your boost at or below 10 psi you will have plenty of fuel, no need for a programmable ECU. I have tested this on many cars with a wideband and haven't found a single exception.

Keep boost down and you will be fine but why risk it? Get a new ecu asap!
