There may be a boot leaking connecting the intercooler or the intercooler may possibly be leaking.....the reason being everything was ok until the install of the 6.0 intercooler.....thats my opinion anyway.....let us know what you find, good luck......Fred

i had the same prob low boost but after i turned the truck upside down looking for the problem i finally realized it was the line going from my turbo to my gauge it had a hole in it and wasnt reading right at all replaced it and went back to about 25 or so instead of 10

hey johnboy,the line that was leakin on your gauge.this is what i did,i used the neoprene line that was supplied but i went a step further,i went and got 6 foot of copper line that was one size bigger than the neoprene and snaked the neoprene through the copper,stuck the neoprene on the connector at the turbo,the drilled a hole in the firewal and run about 4 inchs of the copper through the fire wall,and were your pedels are there should be 2 or 3 foot of neoprene,this way there is no neoprene exposed in the engine compartment,only at your feet and in the cab
