new to the whole skyline phenom.trying tune for a friend.it seems that the turbos are not making any boost."mines" boost guage doesn't work at all so we hooked a vac/pressure guage to the intake and it is showing 14" vacuum at idle and about 12psi at 5000rpm, but you drive the car and it is a dog on accelleration.supposedly had "new" turbos installed before we bought it.we found oil in the air bypass tube and intercooler from the old turbos going bad.any ideas? checked all air hose/vac connections, waste gates, i a really at a loss on this one.
