Debating between PPK and jb4. Considering just having them do the PPK at the port and seeing how I like it. Coming from a 335is to a 435 so looking to get somewhere close numbers wise to my previous car. If I decide down the road I want to add the jb4 to my car with the PPK, is that possible? Any drawbacks? Would I be adding 50-60hp on top of the 335hp I have with the PPK, or would it only be an additional 15-25HP?
Thanks in advance.

My friend got dinan and had many issues with trying to stack a jb4
He eventually paid to have dinan removed.
Not sure but it will likely be the same issues.
That was on a 135
