I can't get more specific because I keep changing my modification list with some retunes along he way. E/C is great in that they will keep working with you along the modification road.

Les, out of several that track their cars, I would say yours gets a pretty good work out. The only one who may compete in that category is Jim's V-8. So, repairs are expected, break downs are expected. I have really done well, reading your reports as well as others as I have modded my cars. It has saved me a lot of track time using info of what others has done before me. I love to show my cars as well, so they are always looking their best, which is hard to do if tracking them all the time. Every car is going to be just a little faster or a little slower...just the way it is...we are all within 10ths of each as far as 1/4 mile times. That changes on a round track as the driver input becomes part of the factoring. I have to tell you the 62mm pulley is a beast compared to the 65mm. It was like starting all over again...
