Was anyone else disappointed with the effects the DT BPV had after installing it?

Price was high, and from all the hype, I expected much much more. I'm running 15% pulley and DT BPV, pulley was done first, and last night I changed bpv. Haven't driven it much, but from what I have driven it, it feels exactly the same.

Any input?

Needless to say, I'm going to put my 19% pulley on now.

I need to put a grin on this sad face.

 

Maybe your BPVs spring was ok and the original BPV was working just fine? Correct me if I'm wrong but this is a way to compensate for the faulty spring that does not allow the OEM BPV to close.

 

I did not notice much improvement with the "yo-yo" when I installed it either, in fact have heard some people say thier car ran worse. I guess "if it aint broken dont fix it" applies here.

 

+1 on both of those answers, the DT/BPV is designed as a fix for less than perfect OEM BPV's, simply to address certain issues. But like some "maintenance" modifications, for some there was enough of a "performance" difference that it became known as a perfomance mod, even though it was never intended to be so.
