thanks for the answer.... no warning lights, and what really worries me is that knock and clank noise that comes from around the supercharger area when it reaches 3500 rpm (pedal to the bottom) just check oil level on super charger yesterday it was missing half, so I drain it, it had a really bad smell, my local dealer just had 1 bottle in stock. I'll get more 2morrow. I'm also checking the compression on all cylinders around 155 on 4 of them so far (2 left on back are proving to be a pain in the arse lol ) thanks again
