To make power you need air (provided by the boost) and fuel. Judging by the black smoke you got, you have more than enough fuel. Now you need to adjust the turbocharger waste gate arm so it opens at a higher boost level. To reach the 115 - 120 hp with that turbocharger you will likely need at least 1.3 bar (at least 18 psi) of boost. I would suggest watching the Darren Lobb's Youtube vids on xud stage 1 tune.
