the stock knock sensativity is too sensative to get real performance from.
stock settings pick up on normal engine noise & electrical noise & limit boost.
all the profesionally modded APCs have less sensative knock detection.
I have done resister & cap changes in my APC & have all 3 pots turned all the way up & I never get audible ping although I have taken other measures to assure there is plenty of fuel & the timing gets retarded enough under boost,the IC is not full of oil & restricting the turbo also a good IC fan is needed free flowing air filter to keep turbo intake restriction down & that the exhaust is capable of flowing enough to get rid of the heat.
I would say to begin with put a 3bar fpr on it at least & turn F 1/2 turn CW & P 1/4 turn CW & set base boost at 6.5 lbs you will get a noticable increase in power & not loose fuel milage & will still have stock knock sensativity later you can go with bigger injectors & all the rest of the goodies bit by bit
take care & have fun
you are in the right place for info
