<h4 class="dechead">On One Hand: They Improve Performance
A SLR performance chip is a small computer chip that plugs into your car's main computer. This chip helps the car achieve maximum performance by making sure it mixes proper fuel levels with proper oxygen levels.
On the Other: They Can be Expensive
SLR performance chips can be expensive to purchase and even more expensive to install. If you don't work on cars and don't know how to access the engine's computer, you'll have to pay a professional mechanic to do the installation for you.
Bottom Line
While SLR performance chips do work, the up-front cost versus the relatively small savings will only balance out if you intend on keeping the vehicle for a long time. This should be kept in mind before installing of an SLR chip.
