But don't be surprised man

. I wasn't at all when you told me those numbers. An exhaust is not going to make you run 200 whp for one hope you weren't dreaming about that if you were I can see your frustration. I think the rx8 in california are on a different flash that probably provide less power due to emission requirements. That could be complete bullshit though but hey it's an excuse.

That header you're planning on getting isn't going to change much either, you need proper tuning, tune the afr's as you please the leaner you go the more hp you would get. Nothing is wrong with your car just accept it.

OR just do what the above poster say and get a turbo in there, only way for now.

hi there, I've had the RAC out today as it's all new to me with the Rx8 running etc. But basically I had the engine light come on this morning so RAC came out and carried out the necessary checks and told me it was running lean is this going to cause me a problem or do I just accept it etc many thanks
