lightning g6e turbo Member 83 Member For: 14y 1d Gender: Male Posted 07/09/12 09:38 AM Share Posted 07/09/12 09:38 AM Holy s@#t, I hope ( sought of ) that there is an easy fix problem with this, looking to get my car tuned very soon with Clinton and I was hopeing for around 300-305rwkw. Mate as said here I would check the exhaust I would think that Clinton could tell whether the injectors are the problem while tuning it, but I could be wrong.Clinton is from what I've heard pretty swithed on with these cars,so if he thinks its the vavle springs then I would probably be inclined to go with him on it, the other thing is of course he was there and non of us were, this is why I say maybe listen to him.that's not to say that the suggestions here arn't good ones, they are, just we are all guessing he had it in front of him on a dyno.I hope what ever it is it's an easy fix.Good luck mate. 2 Link to comment Share on other sites More sharing options...

I have confirmed with him though its got plenty of fuel, so its either the springs as we suspect or the cat. I am pretty sure its not the cat because its only twelve months old and clinton didn't mention it but is there a quick way I can check? We will know soon enough. I'm pricing up some springs as we speak. Link to comment Share on other sites More sharing options...

matsfgxr6turbo Member 388 Member For: 14y 9m 19d Posted 07/09/12 02:51 PM Share Posted 07/09/12 02:51 PM wouldn't valve springs give it a hump in the power curve as the springs bind then unbind the curve looks nice and smooth so I would think a rooted cat is more likely?
