low boost no#s
I have a 2002 7.3L with a TS6 controller with a AFE intake a straight pipe exhaust and my boost gauge read about 8# max and egt climb pretty fast. Does this sound like a bad actuator.I have my boost gauge line tee on the intake where the wate gate actuator line plugs on.

Does it run/accelerate fine? EGTs will come up but shouldn't sky rocket? Is your boost ref Teed into the black line to the intake or the red one? Also, if either, why is it there?
Finally, if your EBV is activating, you will get lower boost and EGTs will come up quicker.

First I just installed the gauges yesterday
Second yes it runs good crusing 600 to 700 but if realy get on it it will climb to 1200 in less than 1/4 mile probally egts are pre turbo.
Third I unplugged my red actuator line from intake and put rubber line on nipple on intake then plugged tee in then plugged red line back on tee. Reason for that that was all I had at the time to hook it up. I plan on moving it too the the map line .
finally I am not sure what the EBV is .

Edit: BTW, I meant green line to intake or red line in my other post. Black line at MAP would be correct.

I just noticed that Jody's wouldn't reach the 1250º mark quite as quickly....
