I went from APR K04 > LOBA LO412 (hybrid K04) > PPT EFR7163, the different between K04 and LO412 was very impressive and it was fast as APR GTX kit but for sure you need WMI and custom tune to get the HP level similar to APR GTX. Here in our country we don’t dyno to see how fast the car can go after mod but we time 100-200kph instead. For mine APR K04 did mid 10s - low 11s, LOBA LO412 did mid 8s - low 9s and PPT EFR7163 did low 7s. 7163 is another world that I’m scared to WOT sometimes but LO412 is fast enough for our FWD car IMO.
I don’t doubt it can make power. Did you log it on a race track for a 20 min session or just a few highway pulls playing rice rockets? That’s the difference. It depends on what your use for it is. I’m not focusing on drag racing.
