All RIPP Superchargers systems come equipped with larger plug and play injectors (if required), a plug and play MAP sensor and a plug and play tune through a DiabloSport programmer. This, combined with a 6-8 hour install on most systems, makes RIPP the best choice for your vehicle hands down. All kits come with all necessary components and everything you need to safely install and run your vehicle.
With well over 5000 kits sold worldwide and over 300,000 miles of collective data logging the short answer is no (providing the system is correctly installed). RIPP has taken every precaution to ensure that your engine is running within safe parameters. RIPP does not squeeze every last bit the engine can take and is rather conservative in its approach from hardware to tuning. That's why RIPP Superchargers is so popular among Jeep enthusiasts, they know they can rely on its engineering and reputable name. Secondly, consider that simple Google searches yield personal end user write-ups on RIPP products from install to towing to daily driving. The RIPP brand has the reputation its competitors wish they could buy through marketing.
Yes, simply because it takes advantage of both the extra air the supercharger provides and the boost. By properly programming the engine and transmission via the preprogrammed DiabloSport tuner, RIPP has been able to extract a more efficient fuel and timing mapping, yielding better MPG. In short you won't lose MPG (but it does depend on how nice you are with the skinny pedal). Additionally the Vortech V3si Trim supercharger is simply more efficient to turn that the competitors, which means it takes less crank HP to make more wheel HP. Typically customers will find 1 to 4 more MPG, but they will be able to cruise at highway speeds and get around slower traffic.
The short answer is yes, however, many dealers who have seen RIPP systems will call and actually become dealer/installers. Though warranty varies from dealer to dealer your expectations should be set going in, if a dealer is not performance-friendly, something as simple as a headlight replacement will "void" your warranty. Try to gauge this beforehand.
Most systems come with preinstalled calibrations that are ready to go out of the box (i.e. 2007-2016 Jeep Wrangler), however, certain vehicles may require further dyno tuning as specified in the description of the product. All RIPP Superchargers kits come with a DiabloSport tuner which is preprogrammed with a proper basemap or full calibration. RIPP prides itself on its thoroughness; it knows its customers can drive 2000 miles from home to go 100 miles into the middle of nowhere. RIPP's engine mapping has been tested up to 14000 feet of altitude, 20+ below zero and 130+ degrees in the desert. It's been tuned while towing loads heavier than the Jeep is rated for as well as tires and axles that make any pure Jeeper jealous.
