my boost didnt increase at all with a 3inch hiflow cat and catback (stock dump/front) and k&n panel . It gets to .6 (kg/cm2 , very close to .6 of a bar ) and stops there . Its behaviour is very much like and EBC , ie gets to .6 and stops exactly , no spike , no drop off .
I have nismo gauges and a digital boost gauge on the turbo timer and they both show the same .
my question is I was under the impression theres a stock electronic boost controller . So wouldnt this do what my car is doing and stop any increase in boost above its set level , despite freeing up the exhaust ? that doesnt seem to be what others are seeing
sorry for the mini hijack
