Boost sag despite post-IC signal
I'm taking the waste gate signal after the IC, just befoe the TB.
Boost sags from 14.8 PSI @ 4270 RPM to 10.3 PSI @ 6040 RPM (see attached graph). I'm using a 10PSI wastegate actuator can and a MBC.
Turbo is a 2554R, exhaust is 2.5" FM.
Could the "bleed off" whole in the MBC be bleeding off too much air
or is the turbo just too small to keep up?
If it's the bleed hole, would a 5-6PSI waste gate actuator help because
the pressure on that side of the MBC would be lower and this less air bleeding off?
