I have a 2009 M6 with the cutler stage 2 kit on it(8 lbs). I took it out a couple of weekends ago and it ran pretty good,it had a little bog on the bottom but was nice and crisp once it got on boost. I changed the primary spring to the cat orange/black. It had a cat gold in it before. Heres the problem, the first pull I make it is crisp right from the bottom to the top. Then when I slow down to turn around and try to pin it again it runs like a bag of ch!t. I shut it off and start it again and bang wicked power till I let off and brake again, then crap. Any ideas? I'm also getting a code ccu when I go from reverse to forward. If I shut it off and restart and don't use reverse it doesn't come back on. I did run it really low on fuel , are the check valves in the tank maybe sticking? I put 10 litres in it and it is still doin it. Any thoughts anyone?
