BUICK GS400 CHIPS
There is no better feeling than smashing the pedal to the floor and having your body pushed back by the G forces that result. With a new GS400 performance chip installed, you can have that feeling more often than before. Your car's throttle response and power will improve dramatically with a new GS400 chip under the hood. To install these GS400 performance chips, all you need is a few spare minutes and a pair of pliers. Everything you need to make your car quicker is going to come with this kit. All of the GS400 chips we sell are made just for your car and will pay for themselves in no time at all because of the savings you receive at the gas pump.
