| What boost level did you make that power at and on what dyno? Without physically seeing your car, I would attribute the issue to one of the following, pending the boost level at which you ran the car: 1. Low compression / poor leakdown results on your engine (did you rebuild prior to putting the engine in your car, or did you just use the JDM motor as is)? 2. AT Cams. You would notice a huge result by going with 500 cams with adjustable cam gears & cam tuning. 3. Lack of a custom tune to realize the power of all your mods.
