So, I just bought the car about a month ago and the upgrades are HKS blow off, cold air intake, and magnaflow exhaust. The car still seems to lag in power in 4th, 5th, and 6th gear. Could it be because the previous owner never tuned it when the upgrades were done? Or do you not no tune with those upgrades?
