Racechip and MPKK

[menelaos]

I exchanged email w/Racechip on their tuner's compatibility w/MPKK.
They told me they do not recommend it. I have not checked w/JB yet but will do so soon. I know Dinan has a more expensive tuner that is compatible w/MPKK.
Please be aware before buying. I wonder if a combination of these will cause "stress" in the engine.

They don't piggyback each other. Certain aspects of the ppk will be left working, but it won't be the power of ppk plus power of racechip/jb4, it's one of the other.

Disclaimer: I don't have either on my X5 however I had an N55 335 and had both ppk and jb4 and it was talked about extensively over on those forums and from the burger tuning guys.

Just worried for engine damage, don't care about the overall HP.
Do you know of any issues?

With stacking? No. However, with any mods there is a potential but you hear about these issues and they are far and few between. In fact, I don't remember any engine damage from any of them specifically.

The only things I've heard is the cars have been put into limp mode because the chip isn't responding Well, but you remove it and everything fine. It can happen.

Wow, how can I missed this thread.

It has been done for years on stacking RaceChip with MPPK.
Nothing but a smile on their faces.

Mppk + racechip is a rocket.
