Go with the ProAlfa guys...they do the complete thing, from ECu remap to catless turboback to intake...then...while you are there let them measure up the space for a new custom intercooler...with the GQV you don't really need over 300bhp...things will go wrong, like clutch 1st and then lots of heat so the ECU will step in and cut boost/timing and you'll start getting errors.
Here's what I'd say you must do, budget depending of course, as it seems you are very excited! lol...
Pro Alfa Tune, try and get in touch with LJ and go for a spin...to see if the power is up to your standard(coming from a Clio)
Get the exhaust and the intake from ProAlfa.
Get them to mock up an intercooler...this will help drop pressure and drop temps...keep the boost at 1.5-1.6 overboost...don't go over. Always remember to put in Selenia Sport Power oil, especially when your car is tuned do it every 5-10000km.
