well here it is,,, something quite interesting and contraversial,,
stock 33 GTR boost in and around about 11.6 psi or 0.8 bar
with standard airbox and exhaust
now take of the airbox and exhaust and replace with aftermarket stuff and because more air is getting sucked and blown the stock internal wastegate is too small to bleed off enough exhaust flow to keep boost at the required pressure....
and because of this your boosting more than normal rising to about 1.1 or 1.2 bar - 16 - 17.4 psi....
so the 70 or 80 bhp you gained from the mods only maybe half half the brake is gained from the mods and the rest is the boost getting turned up or rather not bleeding fast enough,,,
dont know,,,,has onyone recognised this before?
