This weekend we played around with my buddy's car , he just got his RR 2.75 upper on, Diablosport Chip, and 100mm idler and 74.5 gates belt, he also has full bassani exhaust, Accufab T/B, and Amazon CAI. We took his car out and doing a 3rd gear pull the car will make 14 lbs or a hair over of boost but as soon as the tach hits a little over 5000 the boost starts to drop and eventually drops to a little over 12 at redline, we know he is not getting belt slip, so what else could it be, it seems as if the boost pressure is being bled off or something, its supposed to have the boost bypass incorporated in the chip, I dont have the aftermarket guage like my buddy does so I cant tell if mine does this. There has got to be a fix for this since I have heard people say that there car holds boost up top, either they are fibbing and their car does drop boost or I am missing something, whats the fix? Is the Nitrous Pete dump valve mod the same as the boost bypass mod or just unplugging the sensor??
