Can a dealer check if the full boost is being reached on my MY05 STI with PPP fitted. Concern that either I have got used to it or the power has dropped off slightly. Doesn't seem to pin me to the seat as much any more (maybe my bones have thickened or something). Will be taking it in for an oil change at 5000miles (now at 2500) and though I would ask them then. any thoughts from you lot ?

 

yes they can but get then to check that you are getting 100% throttle get them to do a d check

 

Cheers mate.
I have checked the throttle cable for slack and there is very little, would that still mean it may not be registering full throttle to the ecu ?
