got a bit of a weird problem, at first i thought it was coilpacks going on me due to misfire but it seems to be flat spot rather than misfire as i checked coilpacks (splitfires) and changes to new bcpr8e plugs
randomly when i give it, it would hit 9/10psi and in next gear it would only hit 5 or so psi.
using a turbosmart bleed valve with factory turbo.
can anyone suggest what may be the issue? i've been away from turbo cars for too long so i've checked the most basic things but then its beyond knowledge to further diagnose.
photo below of how the boost tee is setup, is this correct? it came with the car this way, i've only turned the boost turn as it was running 15psi before.
i've read the DIY thread but it seems the guys are getting the pressure source from the cooler pipe after the throttle body with the factory piping, mine doesn't have that
Note: the other line (that doesn't go to wastegate) is connected to the pressure source from the plenum, not throttle body. bottom hose of factory solonoid has been removed,
its probably something simple/silly that i just can't see
