For starters I'm running JoeP's MBC peaking at 11 PSI and settling to about 9psi. To make a long story short I was turning onto a on-ramp and started to accelerate (spl?). I shifted all the way through third with no problem. I shifted into forth and the RPM's were at about 3800. As I kept accelerating and at about 4000rpms the car started to buck a little and felt as if not all the power was getting to the wheels. The RPM's didn't seem to climb like usually do. It seemed sort of sluggish too. Anyone know if this could be my clutch going out? Maybe it has to do with the shity mapping the ecu has. I don't know what the hell it is so I took off the MBC until I know what the hell happened. Thanks for your help, Evan
