stage 2 turbo and safc before and after.
This was stock turbo with 680s as secondaries and nothing to controll them. a/f was super rich from 4k on. 11psi... stock tid.
and here is my dyno sheet from today with the stage 2 turbo at 10psi. My top mount inter heater was crazy heat soaked. added safc and 3"tid.

hows it goin people...
ok here is the deal:
i noticed my throttle % (hooked up to my boost sensor) on my safc is wiggling all over the place.... so i went to sensor check. In that mode it shows the imput voltage from all the sensors. Well the boost sensor volatge is jumping up and down... .35 volts or so. It does it at idle, crusing speed.... all the time it does it.
The jumping around is pretty fast... i can see it on the monitor mode when i put it on the graph. The wave up and down on the graph looks exactly like my dyno sheet. My hp and torque have the same wiggle.
here is my dyno sheet so you can see what im talking about.
Im wondering if the boost sensor is causing my timing to fluctuate, causing my dyno sheet to be how it is. Im not to happy with the idea that my timing is up and down like it seems to be.
Any ideas?
