1749vb is a good match with right injectors and FMIC and obviously a map, if you have those and run out of power with it you must be up near 200hp? You need to be on 4 pot flywheel for clutches as well.

You can go bigger but will be more laggy.

you need to do more than just increase air throughput...

if you throw more fuel in, with everything else stock to generate lots of black smoke, you'll get a fair bit more power, without even getting your hands dirty :)

For now they are on 150 hp 

In the map i gave 80% of fuel I would like to give more 20%

the injector is stock, the clutch has a few kilometers and for now it's fine

But the problem is the pression of turbo that often changes alone from one day to the next...

I think it's the fault of geometry

What do you mean for FMIC?? @Sausage

Your advice is always welcome!!

ooh, someone's gonna do some calcs... don't forget you can move the pressure sensor, blowoff and dump control to right next to the inlet valves. reduce down swept volumes, speed up flow, increase pressure. Mmmmm. Poweeerrrr.....

go read some books... way too much to write here! 

good first book would be this. old, but still fresh. it cuts out a lot of the physics and maths, with just the juicy bits. "david vizard how to build horsepower". it was required reading at my college.
