On a C5 Corvette we installed a A&A supercharger kit. The car is still having a strange issue of dropping power at 5200 rpm like clock work. No misfires, the afr is on point and everything seems fine.
Since it was a 1 bar map sensor we couldn't read the boost. We swapped over to a GM 3 bar sensor and updated the linear/offset to the according specs and we still max out at 105kpa. Is there anything else we need to change over to read higher then 105? We're trying to see if the car is losing boost at 5200 rpm.
Anyone have any ideas about the power dip at 5200? It actually rebounds around 5500 and will pull to redline without any issues. Made 511rwhp
