An update to my tuning experiences. The boss manifold was installed, WOT the car felt fantastic, I was seeing somewhere around 51.7 lb/min at 7800rpm with no VCT tuning running E20 and around 29.5-30 degrees of ignition advance. However, once you try to drive the car normally, it misfires and breaks up real bad just partial throttle driving below 3000 rpm. The interesting thing is if I drove the car at partial throttle above 3000rpm, the car drove just fine. But keeping it around 2500-2750 during cruising, it would misfire and break up really really bad. Not sure what the deal is. I'm sending the manifold to a buddy of mine who will do some more tuning and testing, see if he experiences the same issues on his car. This thing have proven to be quite a pain in the arse.
