One thing i want you to notice your ECU has the pulley size labelled on it ;-) 140mm..... now 140mm on the asa unit is 5.5-5.9 psi of boost, i promise the kit you have is the 450kit.......which is rated @ 5.8psi, so that ties in :-) im certain it'll make close to 460-465bhp however....
im not trying to be an ass im just pointing out that you do infact have the 450kit :-) And if you do infact have a higher boosting pulley your ECU in your car is tuned for 5.8ish psi as it clearly states "pulley 140mm", which means any boost over this will cause a dangerous lean condition.
