hi ive got a v9f charger on a 2.9 with 268 cams, when natuarally aspirated it made 217bhp at stealth and has run 14.4 inn road form. Currently making 294@6600rpm with 6psi, going obd2 with different map rev limiter to 7200 hoping to see 300+. can anyone tell me why i am not making 8psi? where I can get a replacement belt from for the charger? and have you seen 14.4 from a road going naturally aspirated corrado vr6?
