Yeh i noticed a good amt of increase set it it at a modest 15lbs in 2nd and max at 19 , i need to do some finer tuning (running really rich, the evap hose that always has an issue of coming off on the 03 had been disconnected on my last tune so need a wideband and better tune) but i really noticed the difference but will need to install and tune at the same time w/ any ebcs.. good luck keep me posted
I asked because I'm curious how much tighter boost control you see with the GS EBCS. Looking to install one before my next tuning session.
you asked who does my tuning.. Most my tuning is done by FTW in eugene spent a good couple hrs each time lol
who did your tuning?
