He wouldn't be able to peg it at 29psi if he had a leak, blown turbo, or bad guage.

I'll drive it more tomorrow and get some more readings. I'll try to video the results if I can. I am definitly going to get the pyro relocated to pre turbo.

 

Well I got the pyro probe moved today. Everything seems normal now that I've driven it more. I appreciate the help. I am ready to do some mods now.

 

The turbo needs a load of some kind to get motivated, it sems. Idle is always 0. Below 1500 rpm's normally 0, unless pulling. Above 1500, it will start to come up. No load may be less than 5 at 55. With a load, flat land, I see about 7 psi, 600-700 degrees, re-turbo.
I have 4.10, HO. I think these are average numbers. Most I have seen on the boost is 19, but I seldom push it hard.

 

good luck shutting down at 0-50 * youll be sitting there for a lifetime

 

I got the probe moved pre-turbo yesterday. It seems to be normal temps. As cold as it was yesterday, I didn't have to wait long to get it to shutdown temp.

My boost stays at zero unless I'm going up hill or I am really getting into the go pedal. I pegged it at 34 psi yesterday.

 

What kind of gauge did you get? My needle is never at zero unless I'm idling. Are you sure it's at 0, or are you just saying that it's pretty close to that.

Good thing you moved the pyro to pre-turbo. Post-turbo doesn't really tell you anything, you'll melt your piston before the gauge tells you.

 

I got an autometer 0-60 psi gauge. It may not be at zero but it looks to be that way. Could my gauge have a leak?

 

Yea it probably does. Try this. Drive at 65-70 mph on the freeway on flat ground and let us know how much you're boosting. If the needle still shows 0, then you definately have a leak. Make sure the ferrule on the tubing that connects to the gauge is good. Next step would be to get new tubing (runs about $6 at Autozone).

 

Will do. It'll probably be a few days before I can hit the interstate.

 

Sounds normal.

I dont get PSI when cruising unless im at about 65mph or higher. Fairly flat land here in AZ.

 

Ok, sounds like I am good then. I haven't been able to cruise at 65 on flat land around here. When I have a chance I will. I'll let you guys know what I get.
