i have a 3 inch exhaust with large dump pipe, silicone intake with K&N filter, but only the stock TMIC at the moment(hopefully a STI version soon.)
the headers are stock.

i have wound down the boost to 15PSI just to be safe for the moment.

how does the tune affect how the turbo spools up?
the turbo is dependant on the air coming out of the engine, which is only affected by rpm..??

thanks, steven.
