My mates problem:
I have a rb20det with:
Front mount
Exhaust pipe
Front facing plenum (makes it run rich)
Boost controller, running 14psi (my cure to the rich problem )
It runs mint as when the engine is still cold after start up for a while, then when the engine is up to normal running temp it looses its pull, lmost like a miss.... It still has full boost but no pull?
I have no idea how, i have new coil pack, new 9mm leads and sparkpugs... always runs good when cold though and just dont know why any ideas?
