Very nice Beast

Bryn Roberts

Have been seeing your posts on RS3s and Golf Rs and thinking what good numbers - but this shows a good B5 takes some beating. Missing my RS4!

Jake Antoniou

This RS3 8V Gen2 has full 3.5 turbo back exhaust and panel filter. On the stock map with these parts on this did 400ps 552nm

On the MRC Remap and Stronic rmeap this went upto 494ps and 696nm.

Thats a gain of 94ps and 144nm, with just the remap.

Jamie need to sell yours and get a new one

Petrit Jash Vincent Gruter

No crazy gains on this one with a exhaust upgrade and stock software like others claim 🤔 AAshley Richardson

Wow what kind of figures can I except for my RS3 8V with just secondary decats bhp/torque wise with MRC remap?

Should fly now 😎😎

Josh Bias-Ely

Bet it flies now Damian Mac Donagh 🙌🏻

Tim Radley

Neil Waudby ^^^^^

Nice work guys well done. Hopefully Damian is happy with it

That power drop at 6k is insane

So it makes 540 at 6k then drops off a cliff! Basically after 6k it's useless... Quite obviously tuned for show... very surprised people think this is good..

Judikaël Lemée

How about gearbox ? Taking 664nm for dq250

Ricardo Alves Araujo Dany Pinto 😂😂

What sort of clutches is running on ?

Łukasz Garbacz na Armie : P

Callum Hall

This Audi S4 B8 is on 95ron fuel and did 331ps 457nm stock. 

With the MRC Stage1 Remap , Stronic remap and filter it did 426ps 532nm

Comment on Facebook

The difference quality fuel makes,that's well down on most of your other ones.

How much is the MRC remap, stronic remap and filter?

Jose Garcia Casado

This Audi S5 Facelift did 332ps and 449nm on the stock maps.

With the MRC Stage2 Package and MRC Stronic Remap it did 473ps 593nm

Comment on Facebook

That's a hell of an increase 441bhp lol

I know some Audi engines coke up but 32hp is ridiculous..

Mark Caster first thing I'm getting done 👌

Mark Hausmann

Was that with smaller pulley ...

What’s the price of stage 2 with stronic please? I presume it’s the same for a S4 B8.5

I have exactly the same car, can you let me know how much it costs and what's involved to go stage 2. Is it just a pulley that's needed for the hardware?
