i bought my r32 about 3 weeks ago and from day one i had this miss at about 5000 rpm so yesterday i serviced it put new plugs oil , oil filter and threw in a dual stage for good measure (hehe)and i then threw the car on a dyno after a few runs i got 155 hp @ the wheels but it was starting to lean out and ping so we backed off the timing and lowered the boost and i ended up with 140 hp@the wheels my R31 had 110 hp@the wheels with zorst my question is why is my car is a barge take in to account that it has the following mods cat bak zorst hks filter sard b.o.v 13psi of boost i would have thought the car would be good for atleast 160 hp @ the wheels
