Livernois looks like they have had some good builds and is a good company. I chose LPE because of the name and the reputation. I could have thrown a cam and smaller pulley on and got bigger hp numbers but they tune their packages for longevity. Thats why you see their 650 package is pulling the engine and replacing internals when others are just adding other components and upping the boost. I think both companies are good but LPE was a good choice for me and it was the best one I could of made for myself. Good luck with your choice
