If you upgrade the engine so much that you need a bigger MAF than the stock, you actually need a custom chip to extract all of the potensial of the engine.
I would go so far to claim that its potentially dangerous for your engine not to have it mapped if you run a high output.

Mapping the engine goes fearly quickly with the right equipment. It can be done on the road with in a couple of hours. ES-tuning in Norway made a special map which is in my car. It goes all the way up to 8500rpm instead of the stock7000rpm. Great for high-reving engines

can the standard valve train take those sort of RPM's?

[Mihnea]

Greg, no it can't, or at least not for a long time...

@OZzzt: what software is that? 90 degree advance at part throttle? U guys must be mad somehow!

you tell me about custom chips? I think you don't know who I am

[OZzzt]

Greg_S: Some maniacs here in Norway run close to 8000rpm with hydraulic lifters... I have mechanical lifters with titanium springs

Mihnea: Each degree of preignition is represented with 2 points. So 90 on the ignition map is 45 degrees, 40 is 20 degrees...
I believe the program is called Race, but I've never really taken a hard look. I just drive the car

...and Mihnea. I have no idea of who you are I just ansvered your reply on my 4" MAF-suggestion.
In less than 2 hours on the road we mapped both ignition and fuel on the 8500rpm maps from scratch on my 500hp+ car.

What are the prices for a M5 Maf these days?

[SteveH]

Not sure many folk consider the M5 Maf now, the blow-through or Prj's RS4 conversion seem to be the way to go.

[Tonks4x4]

Or aftermarket as there is no need for a MAF at all

[rs2coupe]

mtm replica

[recall]

Or aftermarket as there is no need for a MAF at all

aftermarket is the way forward with a nice 4 bar MAP sensor,

[rs2coupe]

I would say this is too much
