lost 10lbs of boost when i swiched to a hot rod vp
i lost 10lbs of boost when i swiched from my stock vp to the hotrod vp im clue less as to y this is. i was gettin 38 psi with the old pump and after the instal i could only hit 27 with my quadzilla all the way up i can hit 31lbs but very rarely its the stock turbo and it dose have some shaft play also i noticed my quadzilla with the stock tunes isnt as intense as it use to be like on my old pump any tips would help i couldnt find any holes or cracks any where also i have played with the timing on the quadzilla and it works best set at zero timing. my old stock vp blew more smoke than my new one with the quad have had a map sensor code a while after the new pump but it hasnt come back yet since then. i have a new sensor on the way
my truck: 2000 dodge cummins 5'' mbrp, raptor 150 running 30 psi, quadzilla adrenaline stock tunes, hot rod vp44, afe stage 2 intake, 1/2 inch fule lines, 35's
