Well if you're running more fuel - you will want more air to burn with it, otherwise you'll just chuck all the extra fuel out the exhaust in the form of black smoke.
Using a manual boost controller, you can increase the maximum amount of boost the turbo will make before opening the wastegate.
You will want to balance the two of these to increase power and retain economy.
A boost gauge is 100% needed to adjust the wastegate.
25psi is relatively safe on standard turbos, then increase the fuelling to match - ie turn it up until you have a very slight haze on full boost, back the fuelling off if you're smoking everywhere.
expect to make around 120bhp with these two adjustments in balance.
