My R33 GTR, basically stock except for exhaust and (now) HKS IC, suddenly is about 0.2 bar low on boost. It used to reach about 0.85 or so, now I am lucky to see 0.6, today only 0.5
There are no leaks with the intake pressurized after the compressors. No exhaust leaks, no smoke from exhaust. One day, full boost. The next, low boost.
I have not done any real diagnosis except for replacing my FMIC and piping with HKS parts, and doing a pressure check. I guess the next thing to check are the wg actuators and piping?
Any ideas with be greatly appreciated!
