well nothing cheap is going to be fast, nothing fast is going to be cheap. that being said
how about a cheap mbc if you dont already have one and turn up the boost? without getting a larger turbo or better manifold a external wastegate and a tune you are slightly limited.
so doing small steps now like upping the boost that will be a start i doubt your turbo is out of its efficency at 15lbs
