Bigger intake, new Up Pipes, All new Boots and Clamps, Presssure Regulator Changed.WOT Only getting 11psi Boost at 3700 rpm.This was done in Performance setting on the SCI. Anybody have any thoughts. Shop I had do it pretty Reputable, But Closed until Monday. Thanks Rick

Check for up pipe leaks or intercooler leaks,what's your EGT's WOT?

Wot egt is about 1150 or so

Any other Thought before I bring it back in would be appreciated, Thanks Rick

Disconnect the wastegate red hose and slide it into the Intercooler boot clamp stud. This will check to see if the waste gate isn't properly adjusted.

How are you checking boost? Mechanical gauge or an electric gauge like a cts?

Using an electric gauge of SCI Livewire,Thanks will have the shop check it out in Morning

You may have a map sensor not reading right or something. 1150 egts is pretty low for not having any boost. Try checking with a mechanical gauge. Also make sure the map hose isnt kinked, cut, or plugged, as well as the map port on the intake. May want to check map vs ebp and baro koeo to make sure it is reading right, should be damn close to what ebp and baro are koeo.

Weak HPOP?

Checked it with a mechanical gauge comes up to 24psi now all good ,Thanks for your help
