Ok so I have a 90 12v cummins and I put an intercooler and an hx-35 off and 2001. After I done that the truck is runnin way high egts and I can only get 20psi of boost. So I'm guessing my question how do I get lower egt's and how boost? Can someone please help me out? Thanks

 

I have bigger injectors with 4" exhaust with hx35 on my '93.... and I can't get the EGTs past 1100-1200 or so. I wish I had a boost gauge to know what I'm making. I do have a adjustable boost elbow on it... supposed to be able to make up to 35psi effectively with a HX35. I haven't adjusted it though since it came off my buddy's '02 truck. He probably set it higher than 20psi though.
