The Big Gun Power Box is a plug-and-play fuel controller that allows you to properly tune your fuel injected motorcycle, ATV or Side x Side in just minutes. Installing a Power Box allows you to get the most out of your aftermarket exhaust and increases throttle response. A Power Box helps cure the lean issue that is run into when installing a higher-flowing exhaust and comes pre-programmed with a middle-of-the-road setting already into it, making it easy to install and go ride.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eIncreases horsepower and throttle response\u003c\/li\u003e\n\u003cli\u003eInstalls in minutes\u003c\/li\u003e\n\u003cli\u003eThird generation technology\u003c\/li\u003e\n\u003cli\u003eNo computer needed to adjust EFI\u003c\/li\u003e\n\u003cli\u003ePlug-in technology (Does not interfere with stock ECU map)\u003c\/li\u003e\n\u003cli\u003eIntegrated faceplate buttons provide easy adjustment\u003c\/li\u003e\n\u003cli\u003eHighly recommended for any EFI unit with aftermarket exhaust\u003c\/li\u003e\n\u003cli\u003e2 Year Limited Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cbr\u003e\u003cstyle\u003e .table-biggun1 { border-collapse: collapse; border: 1px solid #000000;} .table-biggun1 td { border-collapse: collapse; border: 1px solid #000000; padding: 5px 15px 5px 15px; } .table-biggun1 th { background-color: #BEBEBE; border: 1px solid #000000; padding: 5px 15px 5px 15px; color: #000000; } .table-biggun1 tr:nth-child(even) { background-color: #E0E0E0; }\u003c\/style\u003e\n\u003ctable class=\"table-biggun1\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2011-2014\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003ctd\u003eRanger XP 800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2011-2014\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003ctd\u003eRZR 4 800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2011-2014\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003ctd\u003eRZR 800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2011-2014\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003ctd\u003eRZR S 800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cp\u003e\u003cstrong\u003eBrand: \u003c\/strong\u003eBig Gun Exhaust\u003cbr\u003e\u003cstrong\u003ePart Number: \u003c\/strong\u003e40-R54H\u003c\/p\u003e"};
