Ya know I have never seen so many people that would go to so much length to be so cheap. Hey if you are concerned or convinced they don't work don't buy one, save your money. Do a search on Sprint Booster and read all ( and I hope you have some time because there is a lot ) the posts and you will find only a couple that bought one that did not love it. If drive by wire lag does not bother you forget it but if it does I know of only one way to fix it and that is the SB. One reminder, the SB does not add HP.. But It does add

power.
By the way if you own a sports car and want to do mod's on it and $300.00 is an expensive mod for you then maybe you should rethink what you want to do because a nice shift **** is about $100.00 and aluminum door lock pins will be about $40.00, don't ask about ECU remaps or pulleys because they are way over $300.00. JMHO
