i would have said IC... but since you said no. then no.
It's wise to put an IC on becuase of detonation possibilities. Plus the only way you will really get more HP is if you either take in more air (ie bigger turbo/ intake) , cooler air (ie IC), more fuel larger injectors or better fuel pump.
now.. all this is in consideration that the a/f ratio has to be watched, becuase you don't want too much air or too much fuel.
the only thing i can see now is to get the air cooler going into the TB..... then mess with the fuel and air ratios.
good luck
