About 2 years ago I installed a head and cam kit on my 08' with a PCV. She dynoed over 200+ on that humid day. I just had a new head gasket and new cam caps, but the local dyno shop only pulled 185 on it recently on an ugly humid day here. Installed new Brisk plugs, all the heads are good. The dyno tech did state that their unit is off by 10-15%. What else should I be looking for? I'm willing to head to another tuner anywhere on the east coast. I'm in MD, but need to get this thing dialed in right.
