Boost question
 

This may sound like a stupid question i had my fd map finished on Wednesday we stopped at 0.9bar or 13psi which gave me 380bhp 314lbft which im really happy with would i need to adjust the gain on the profec b spec 2 if i wanted to up the boost to 1 bar or should i leave it alone i just want to see what sort of difference it https://cimg0.ibsrv.net/gimg/www.rx7...7415c0ac5a.jpg
