For sure butt dyno will be noticeable...the throttle tip in, remapped A/F will all give you the impression you've got some "hmph" under the hood.
I've read similar assessments from the E90 owners who had it done...
However, the Dinan tune seems to be more "impressive"...
For me it's a cost/convenience thing...if I move out of the area, I'll probably get the PPK. If I stay near my current dealer, I'll get the Dinan.
