I got my tax refund. I would like to install a perfomance chip in my '05 Ranger with a 4.0L V-6. The one I found promises a whole 12hp...not a whole lot of bang for my buck quite frankly. I know there has to be a chip out there that won't cost me an arm and a leg, yet, give me a few more ponies than a puny 12hp... I know pretty much anything I buy will include the standard options (performance, towing, economy, tire size, speedo adjust, etc.). Any suggestions, or, should I use the money for some cool optics for my AR-15, or give it to hard-working, single mothers who can't afford clothes (strippers)?
