An engine control module (ECM) PROM is a removable chip that has several features. The 4-Bank Performance Module from Bully Dog is a special kind of ECM PROM that can do computer programming and modification "on the fly." Most programmers need to be used while the vehicle is parked for accurate adjustment, but when you need a speed and power boost while driving--on the highway or on the track--the Bully Dog 4-Bank Performance Module is what you're looking for. This unit includes six position settings, which are high idle, valet, stock, +50 horsepower, +75 horsepower, and +100 horsepower. The Bully Dog chips utilize cutting edge programming that keep exhaust gasses cool and increase power. An additional benefit of this unit is that it removes the speed limiter, allowing you to really open up the possibilities for your engine. Over time, even the most solid vehicles will require maintenance cycles and repair of broken parts. Some find that the most difficult aspect about working on a vehicle is the search for a dependable source for reliable parts.
