Hi i have got a gen 3 twin turbo runing standard turbos with a hks exhaust induction kit and chipped ecu.
Some times the second turbo just wont kick in a 4500 rpm and the next day it will be fine, and i have noticed it only boosts up to 0.5 bar all the time even when the turbos are working ok. It is a blitz boost guage so i thought it should read accuratly.
Any help will be much appreciated, thanks.
