Typical Turbo psi for Tuned 6.0

[rb12405]

Good morning fellas... I have an '07 F-250 with 47k on the odo. Currently, it has a 4" TB exhaust, and custom tunes from Matt @ Gearhead. I use the edge CTS for my monitoring. I already have a bad FICM (reads @ 27.0v to 31.0 on startup, and eventually gets up to 47v after a few miles) but now it seems that all i can get from the turbo is 21 psi @ WOT. I run the SRL tune, but even with SCTs performance tune on the 3015, it would max @ 21 psi. I'm not looking to add more boost, but I do want to make sure that I don't have a problem. I have read that some of the guys on here can get 28 or 29 psi. Any suggestions are greatly appreciated.

I see 27-28psi tuned at WOT.

First thing you need to do, is correct the FICM voltage issue, and check to see if you've dropped an injector already.

Next check your IC boots, and up pipes for leaks that would cause your boost issue.

I haven't done a WOT recently, but when I roll into it good I see around 21-24 avg running SRL. Seems right to me.

How could I tell if I have lost an injector already? Thanks for all the help fellas...

I'm running srl also and I don't see over 24, usually about 22psi at wot.

how are you monitoring all these pids?

Matt told me the edge seems to report a lower than actual boost IIRC

you will see more boost when the load increases like going up a hill or with a trailer in my experience

Mine pids are from an Edge Cts. I think you can run a injector balance from the cts can't you? That should tell you if there is a bad injector. I'm sure someone will correct me if I'm wrong.

If someone can steer me in the right direction for this, it would be much appreciated... Also, what is the most effective way to check for boot leaks around the turbo? Soapy water?

The Insights can't check the injectors, you'll need an AE or diagnosstic comp.

It is worse case for running low FICM voltage, and was mesnt as a word of warning.

My truck approaches 30 with the SRL. I didn't like that without studs, so I went back to stock til the studs get done.
