It is the same.. The problem is also when the car is in netural gear..

Have a problem with my rpm.. When it hits 6000 rpm and I release the throttel, it is werry slowlyto come down..Is that a ECU problem?
SO sorry for my english, but hope you understand my problem

Thanks mr Thunder
Just heard that it is just a straight fit on the faceliftet, not the first model of the S4.. But I will soon find out

Is this plug and play on a pre-faceliftet?

Bobbler.. Do you have the brakes on yours car? And with 18" ?

Will 18" fit under the brake from a RS4 B7 model?

Have a problem with my rev counter. If I run in 2 gears up to 7000 rev and switches off, the rev slow to fall at about 1000 rpm. Could it be a vaccum hose is leaking or is it an ECU error. ?

So the next step would be, Milltek 3" cat back, RS2 sparkplugs, maby a bigger fuel pump, new map to about 1,5 bar?
What about Wather/methanol kit from VAST?

Yes Nige, but isent there a diffrent from 200 cell OEM to 200 cell sportscat.. Or is 200 cell the same whatever it is OEM or sportscat?
What is the best sparksplugs I can go for? RS4 OEM?

Remove the precats and change the main cats to 100 cell free flow versions. At least in Finland those will pass the MOT. Or if you are "afraid" of the emissions, use these 200 cell cats: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=390020368599 I have 100 cell free flow cats and the car passes...

Okay I then have 200 cell cats.. But that is OEM cats.. Wouldent I get some better flow with 400 cell sportscat? It is a Danish company who mapped the car, and some of the best. Would I get the best power gain from a wather/methanol kit, and a complete Milltek system, instead of FMIC and Milltek sys...

I do have the RS4 downpipes (precats) on the car now, together with OEM RS4 system..

No I dont have LWFW..

do you have a LWFW? thought you would be on bigger injectors already. what fuel pump do you have? As for the down pipes do you mean 100 cell cats - a good idea. LWFW? Sorry but what is that. I am running with a RS4 fuel pump. For the down pipes I mean 400 cell sportscat, so I can pass the MOT here ...

Probably a good idea to post the current spec of your car so ppl can see what you've got and where to spend your money for the biggest returns. I can try Nige.. 2,8 NA heads Coated and reworked manifold RS4/RS6 hybrid turbo All intake is RS4 RS4 injectores RS4 intercooler Complete de-catted RS4 exh...

I am having about 450 hp, but more need more

Should I go for a wather/methanol kit or some AWE intercooler?
At the moment I am having some RS4 intercooler.
