1. Raw power/performance - LPE. Their packages make the most power if you have other cars this may be the way to go.
2. Complete Package/Support - Callaway. By far if you are looking for more power and absolute reliability this is the way to go! They have a dealer network, any place in the nation you can get your car worked on etc. It may not be as much power but for a complete package they are the way.
3. Scammer - Hennessey. There is no way that this company should be trusted in any way. They screwed a TON of Viper owners back in the day.

If this were a purpose built car for racing that I could have down for months at a time it would be LPE, otherwise I am going to have a Callaway setup.

I'm very pleased with HPE's work. I have no knowledge or interest in what they are rumored to have done wrong in the past. I've heard stories about every shop in America.
