Default boost seems low to me???

so my boost seems low even on my extreme tune on my edge evo and the most ive seen is 17psi on the evo screen i know it reads off the maf sensor but it should be close right? and i do have the gr38.

17 psi is very low... I would check your up pipes, check the wastegate to make sure its not loose. Check for boost leaks...

You have a 38R on there now? You should be seeing about 22-27psi on your stock or tow settings.

Yes, You can pressurize the system. Compressed air and something like this...http://www.dieselsite.com/index.asp?...ROD&ProdID=607

Wastegate is shown in the picture...

Some PVC, PVC cap, a valve stem and some PVC glue... That would attach to the intake or straight onto the turbo and pressurize the system... If you don't hear the leaks, spray some soapy water on to it and you will see them.
