MSD, can you tell the difference?

I've switched cars from the stock electronic ignition over to MSD units and did notice much easier starting and improved throttle response.Another thing that helped was increasing the plug gap which you also can also do when using the MSD.

I never ran any of the cars on the track but I'd imagine it would have knocked a bit off the ET as it definitely felt stronger,especially at the low end.

I also ran an MSD units on a couple of tow trucks I used to own which helped mileage and performance and I never had one failure over 10 years of daily use.Highly recommended.
