I did not go with the Avstar. I ordered my engine with a Silverhawk and it came with an Avstar. The injection was then changed at my request to a Silverhawk as I ordered it and I regret that change. At the time of that decision I could not get any feedback or reviews on the Avstar. I have been very disappointed with the Silverhawk to say the least. Since that time I have talked to people with Avstar and comments have always been positive on that system. Just my experience.
