If u increase ur pressure! u will need to increase the timing! Thus giving the engine more time to burn the extra fuel! Nice power increase + much better throttle response! If ya cant manually change the timing, the ecu will shorten the injector duration until it hits its minimum setting its programed to do! After this the car will start to run rich! and from what i know from dyno tuning a rich motor runs cool but has less power! A lean motor runs hot but lots more power!
Remember! nearly all aftermarket tuners that put chips in are just advancing the timing and leaning out the mixture for the main driving conditions! Eg: Full Throttle! and leave the crusing program standard!
So keep ur chiped engines well serviced! Oil change's every 5000km!
