1. Switzer Full Exhaust System
2. Switzer Plug and Play (Piggy-Back) Tune
3. Switzer Drop-in Air Filters

Then it will cost you about $7,000.

If you just want the tune, then they will sell you a different package that includes only these:

1. Switzer Plug and Play (Piggy-Back) Tune
2. Switzer Drop-in Air Filters

They will sell this smaller package for about $3,000.

Some notes about the tune:

1. It is a completely plug and play module, which means that you can remove it any time you want.
2. It does not remove the 155mph speed limiter.
3. It does not remove any CEL's you might get from doing a Catless downpipe setup.

According to their dyno sheet, with their complete package you will make about 604hp to the wheel and about 562tq to the wheel. With just thier tune and their filters for the smaller package they are unable to say what results you will have.

I am undecided if I am going to get it just yet, but feel free to make your decision based off this information or you can call them yourself.

Which one is true? It does / does NOT remove the 155mph speed limiter?

I asked to Switzer website and they said it removes speed limiter.. I am confused...

I was told that it doesn't. Hmm...

OK. Maybe it doesn't because it is a piggyback.

700HP & speed limit is nonsense IMHO.

Interesting dyno results. So the P700 makes 68rwhp more than stock. So if you assume 15% drivetrain losses, the stock M5 is making 630hp and the P700 is making about 710hp.

they're not the first. my ECU (ETG) tune is a piggy back(actually sounds like they're using the same tune as mine)

and it produces similar power gains as this one from Switzer.

yes i think thats why, mine is piggyback and it doesnt remove the speed limiter.

but i have no desire to go over 250 km/h
