Bought this for my 01 dakota. I know that most people on this forum bad mouth this chip. I will not say that it makes a v6 outrun a v8, but I will say that if you put good gas in your truck and use this chip, it helped mine whole lot... I bought it about November and sold my truck for an SRT-4. I think that it was a little over $200 shipped. I need to sell it now and need $75. It was only on the truck for about a month and a half. I gauruntee that it still works. Please ask any questions. This installs in about 2 min. very easy to do and for $75, what do you have to lose. It does more than $75 worth of HP increase.
