  • Answer:

    YOU HAVE MAYBE 170 HP... IT SHOULD NOT BE PULLING... APEXI V-AFC II vtec controller IS FOR HIGHLY MODIFIED CARS NOT A B16 WITH 2 GRAND IN IT. I SUGGEST YOU UPGRADE YOUR FUEL DELIVERY SYSTEM IE BIGGER/BETTER VALVES, FUEL PUMP, THROTTLE...AND CAMS YOU SHOULD HAVE PUT 5000 MORE INTO YOUR ENGINE BEFORE YOU BOUGHT THAT PIECE.
