my car feels like its reving up as quick as it did stock but the power delivery feels as if my wheels r slipping or the clutch is not fully engaged. I used to feel a nice difference in power for the first 2000 miles on this setup but all of the sudden, overnight, it doesn't drive as well. almost like I got a bad tank of gas. that's what I thought it was at first so I let the tank run low and filled up at a different gas station and reset the ecu. 150 miles after reset and still no change. I'm confused......
