I can't imagine a sprint booster being considered a performance mod. It is a gas pedal mod, not a performance mod. If you want to change the pedal action, great.
A blow off valve? Seriously? If I heard one on the street I wouldn't be able to prevent myself laughing. I looked it up to see who was selling BOVs for BMW models and saw an advertisement that stated "has the ever-popular whoosh sound". Honestly. OK. Do what you like, it is your car.

As for the blow-off valves, I'm not looking for one to achieve that cheesy whoosh sound, I'm not a Honda kid I more interested in the performance, and I've heard some good feedback from other BMW forums.

I"m going to apologize in advance for this post, but blow off valves and sprint boosters are a waste IMO. but that being said, my name isn't on the registration and i'm not making the payments so do what you want, it's your car. However, don't be surprised when people point and laugh as you drive by.... Sprintbooster... .. from their own website: • Sprint Booster does not increase Horsepower. • Sprint Booster does not reduce your 0-60mph times. • Sprint Booster DOES make your car 'FEEL' faster. (a good car wash and detailing makes my car feel faster too ) • Sprint Booster is not for everyone. I think you forgot to get a tornado air too.

There is a potential non-performance benefit associated with replacing a weaker component on the vehicle with a more robust aftermarket valve. That is a durabilty issue, not a performance issue. Wouldn't think that changing out new parts during the warranty period (thus giving up the benefit of your warranty on the impacted parts) would be much of a benefit.

I wanted to write "If you are serious about mods, find a real tuner (not an 'installer') and ENGINEER a total package: Intake, exhaust manifolds (drop the cats? new pipe), exhaust that captures the upgrade to the manifold, serious DME programming (change the throttle mapping to achieve the sprint booster effect), more efficient intercoolers, etc, etc..."
But I didnt, as my read was this is not a serious player ...I could be wrong, but to REALLY change performance takes time, skill and $$$ Skip bovs or diverters (IMO, a joke unless you go to way larger turbos and the current bypass is ineffective). These engines ARE moddable, but DIY bolt ons arent significant. And I have zero doubt there are people singing the praises of BOVs on forums all over- as there are many people saying air filters give them dramatically more HP. In fact, is there ANY mod that people buy and say "Ah, yeah, that didnt really work". Nope. A PS Sprintbooster may be a perfect product- makes people THINK the car is stronger but actually makes no real changes other that reducing gas mileage. |

I have SprintBooster on my cayenne and I love it! Everyone who has tried it does. It helps drastically when overtaking, and I did not notice a drastic change in gas milage. Especially with the V3, when driving through town, I switch it off, so gas milage is not affected.
As for air filters, I have an AP intake on my cayenne, and the difference in performance can definitely be felt. But I haven't heard of anyone changing their filters on an X5 d, so thats why they are a maybe.
