Big difference in power. I get 3 to 4 mpg more when using performance level.

I recently purchased the Hypertech Max Energy Programmer. This is one of the easiest programmers to operate. I have owned other programmers but this is the best for the money. I wish you could update the programmer without resetting back to factory settings. I would highly recommend this product. A+++
