My dino last year was 162.5 stock , i installed a pc3 , full m10 exhaust and air filter and a gipro engine retard eliminator which should have bumped me to 175-180. but it only read 156 . so i know its wrong . heard thru the grape vine they were all off by like 20 horse . I am having it tuned soon and ill know the correct numbers.
