What are the biggest gains from one another? I think Dinan is 355 Hp and 400 tq. Not sure what the BMW is? Just want to hear from people that have experience with these...Thanks.

By the way I have a 2011 BMW 335i with the N55...

PPK is 320 hp 332 lb torque (auto)

Although these numbers may be underrated

When you tune you risk warranty
PPK does not do that

Also tuning requires greater maintenance

PPK forces dealer to change spark plugs at 45k
Still under warranty

Well worth $1000

You get power and later spark plugs
