Torque produced by large streetport?

there is no problem running the stock turbo with any size porting but like stated above the band will change. Only downfall of doing a nice size port with a stock turbo is controling boost. It will spike and be incosistant with the stocker 8-15-11psi pulls with mbc set @ 10 if I remembered my setup for awhile. this was with 30mm ported s4 wastegate and clipped turbine wheel on s4 t2 with agressive streetport.
