- no significant power gain 4000 - up
- the intake seems to be louder (sucking air in)
- my PPE has a new kind of brabbling when you go off the throttle

You can really feel the power gain. Its not gigantic but you can feel the car more surging.

I am not a fan of timing (so much different things can change from one day to another...). But i reached higher speeds in shorter time

I recommend it to everybody

Very good summary! I stand behind that 110%. It's very worth it and comes in with all the promised results. If you haven't noticed yet, but your fuel econ might actually also increase by, like, 1 mile... hah! Mine did. Higher speeds in shorter time is the best way to describe it.
