Are Performance ‘Upgrades’ for Your BMW Causing Problems?

Picture 004e60 (2)When you put in some performance upgrades on your BMW, whether it was a brand new BMW or something a bit older, you probably expected some great performance. Performance upgrades, by their very nature, are supposed to improve performance, but sometimes they don’t.

There are situations where an upgrade, addition, or alteration on a vehicle can actually impair performance. For example, a person may decide he or she wants louder exhaust pipes but they suddenly become surprised when their acceleration and top speed is diminished.

Altered pipes are actually changing the exhaust rate, which can impact fuel to air ratio. If the engine is not able to expel the exhaust at the proper rate, it’s going to affect performance.

Changing spark plugs is another supposed upgrade.

Higher quality spark plugs are certainly beneficial, especially for high performance automobiles like BMWs. However, changing the gapping, switching out the wiring, or altering the firing system in any way is going to affect performance.

Because of the fine precision of BMW automobiles, any changes to what the factory recommends can have negative consequences on performance.

What can you do to get performance back to peak levels?

If you’re not willing to remove some of those upgrades, it may be necessary to make other modifications as well. Some of these modifications may involve the onboard computer system, and that is highly discouraged.

If you make changes to your BMW, you will likely void any warranty on other components of the vehicle. You will also run the risk of increasing any potential maintenance repair costs in the future.

If you’re interested in certain upgrades, speak to an experienced BMW service technician first. He can give you the honest assessment about how this will impact your BMW.
