I am curious to see if it makes any difference in my 2.7L boxster. One of these days I will go over to Performance Autosport in Richmond where I have my dyno pulls done in the past, fill up the car with the 100 octane lead-free fuel they have there and do a pull. I have done 4 dyno pulls there and the results have been very consistant with the sorts of things I have done to the car. I find learning about the car with dyno pulls great entertainment,
