Car is an 8V 83 900T, MSD BTM set to .8, no APC mods, no IC or WI. Driving the car this weekend, when it was 85+ degrees, I noticed that the car was transiently making substantially less boost than usual - peaking out at 7 pounds or so, tapering down to 3.5 to 4. Other times this weekend though, I got my normal 10 tapering to 7.5/8 Same temps, same driving style, no real rhyme or reason for the difference. I've been driving the car all week and am now consistently in the 3.5 to 4 pound range... I checked under the hood, all vac lines look ok, I dont see any blown-off hoses or couplings. Could I have a bad WG actuator? A bad bpc? Plug wires messing with the knock sensor?
TIA,
CW
