Ever since fitting the straightthrough frontpipe on my 200sx the car is overboosting massively and the fuel cut is cutting in in every gear on full throttle...... However, having put the standard frontpipe back on (leaving the decat and back section there still) its still overboosting. (must have been a co-incidence with the frontpipe). Its peeking at 18psi (a lot for a standard 200sx) and the max it should run is 12psi at the very max. Has anyone got any ideas what else it can be? Could the wastegate be stuck open? The sxoc.co.uk bunch arent too sure either! The car is standard bar the decat/back section and an apexi induction kit.

Help!

I may well have to as it goes! Just spoke to tommy field and he said check that the wastegate actuator isnt stuck? Could that be a possible reason?? I'm about to sell it so dont want to chuck any wonga at it!!!
