.. a first gear pull that tugs at the skin on your face! The performance gains are def. noticable, and the engine runs smoother than before. One thing I noticed though was that second gear up until about 3000-3500 is a bit sluggish. I think I just need to get the fuel map dialed in around that area though to get my HP back. I am very happy over all, the kit is very complete. I have read the u-tune guide about 6 times now, and I feel alright about tuning. I wish I could watch someone that has tuned before take a crack at it for a few minutes though, so I could get a better idea of exactly what I'm supposed to do. If anyone has suggestions or tips on tuning I'm all ears
