wrongo without a bcc( fuel cut compensator) the maximum boost is fuel cut or about 13.7 psi( I believe one bar is about 14 psi) the K&N dows not affect boost the exhaust slightly and the DP the most. with a bcc you will still get 13.7 until you modify the reponse of the waste gate with the vsv mod or t bleeder or an ebc

1 bar = 14.7psi

you can get a aftermarket ECU to increase the boost and HP, it will cost about $1500US for ECU and your supra will gain 100HP and run 1.2bar

No, you will have same boost level as before mods. To increase boost make any of mods listed at www.mkiv.com I used to have T bleeder mode, now I have mbc and boost - 21 psi
