stage 2+ misfire help

[andy1]

Hi i recently purchased an audi s3 r-tech stage 2+.

The car has started to badly misfire under acceleration. Ive had coilpacks, spark plugs and fuel injectors replaced but it still happens.

has anyone had this before and found the cause.
Any help would be appreciated thanks Andy

You really need to get it logged by the people who loaded the map.
As you've replaced all of the simple causes there could be fuelling or timing issues causing your problems but you need it logged to find out what is going on.

How long has it been 2+?
Have you removed the fuel pump and checked the follower at all?
Process of elimination but you really need to scan/log the car.

Thanks for the replies guys.

As far as im aware the car has been stage 2+ for only a few months. The misfire is from cylinder 3 if that narrows it down any ?

Ive also heard it could be my maf. Is that possible ?

Doesn't really help.

You need it logged under load to see exactly what it is doing.

I presume you have a high pressure fuel pump?
