An uprated ECU, boost controller and uprated exhaust system, plus rolling road mapping would this get you to 350bhp on a standard type r v4?

 

if you go for a simtek u wont need a boost controller prob want a cold air induction and decat to see that figure maybe a ported manifold but every car is slightly diffferent i seen 324 with a 100cell sports cat full 3 inch system and the simtek
