Thanks everyone for your thoughts and comments. T5NYW, I certainly intend to leave it as it is. It already has substantially more go than anything I have had before plus making changes to it will more than likely have an adverse effect on the already painful insurance costs.
That said, I will be using the car in a sprint series so the need to be competitive may call for me to reconsider. First things first though, I will be getting it dyno'd and attending some sprint events with the car as it is. If I can be competitive without making any changes to the car then it will remain unmolested.
