Short review on the Switzer P700 Package.

Automobile Magazine has just released a short review on the Switzer P700 Package.

As some one who has driven one and raced one, I can attest that the tune is legit and still maintains the stock drive feel until you really get on the throttle.

http://www.automobilemag.com/reviews...r_p700_bmw_m5/

Hope you enjoy!

Any idea who makes the "Switzer" cat-back exhaust?

I wonder how much just for the tune? Don't need the CF delete (i.e., new air filter) or the cat-back.

Switzer will sell you the tune and air filters for $3,000.

If anyone interested in their complete exhaust system, midpipe & muffler, it retails for $5,000 but on sale now with 10% off.

Bit disappointing - how could they possibly not feel a 140 hp difference beyond pulling on the stocker? Unless they never mashed the throttle in either it should have been obvious.

Stock is underrated.

My dyno reflected 58whp gain and 60+wtq

I sure as hell can feel it. Also raced it against my stock M6 and it crushed it.

Switzer needs more authorized dealers/installers in my area.

Hmmm but I doubt that would get you to 700 crank hp unless the car has 640hp stock.

Still it seems really good. I had a Dinan tune on my 550i and one of the best benefits was that it increased power a lot at the lower rpms which made the car feel more responsive - it was like a catapult effect. would you say that low rpm throttle response has improved as well?

My dyno reflected 597whp on 91 octane and mid 90's for temps with switzer tune.

With drivetrain loss I believe it's pretty darn close to 700hp @ crank.

I wouldn't say throttle response has changed, but you can feel the 560+ torque down low as significant increase from 2.5-4k range

Since this is a 'Piggy back' system, is it at all noticeable to BMW should they interrogate the factory ECU? I'd love to have the extra power but since my ability to use it is kind of limited, I don't want to have a warranty repair denied because of it.

I believe yes, detectable by dealer. The piggyback tricks the ECU into applying more boost. This is visible through an OBDII port reader, like the p3cars gauge. Assuming the car retains peak boost history, BMW could review those numbers should there be an engine issue. Now, would the actual techs at the service dept notice anything? I doubt it.

All speculation though, as I don't work for BMW.

I believe the same as you. One thing for sure is that if one of these motors 'blow' I can almost guanantee that BMW would access the ECU data before giving permission to a dealership to repair/replace a very expensive engine. Not knocking the Switzer product as I'm aware of the fantastic job they do with the GTR platform, just think owners should be aware of any potential issues.

It was up against a press car and rumour has it they use the remapped file that is knocking around the tuners? So if it pulled on a press car it must be quick?

I just read that their own car was the "press" car. I didn't take away that it was "tuned" with the flash that is running around.
