I have heard people talking about going to the smaller tooth pulley to increase boost(28 and 30 tooth). How much boost and horsepower do you gain with these swaps? I am assuming you would need a new tune for that also.

I data logged and sent to Tim at DCX depot. He was the one said I was pulling 9 PSI. Could that data log be incorrect??
