i know it probally doesnt belong in this category but since the vsa helps with handeling and all , is it sacrificing any hp at all when enabled??
It won't actually hurt your hp, but it will hurt your acceleration. A simple rule of thumb. Leave it on during normal driving and take it off when you are driving aggressivelysearch my friend.
yes it will hurt your hp. it's a traction control remember, so when you tires spin, it'll cut fuel response until it feels it's "safe" for you to continue your response. .
