not a big fan of it. First its not really a plug and play unit which makes install a bit harder and second the tuning aspect of the cheap shot and big shot are both not that great. If you need a fuel tuner you are much better off with a lloydz or power commander. I know several people who have used the ness tuners and all of them still have a decel popping issues and the customer support for them just suck!! Hate to say it but you really do get what you pay for.
