Think this should be in here rather than A3/S3 forum!!!
Thought you might be interested in checking out Revo Technik (formerly APR). They have introduced new softare which doesnt invlove removing the ECU and a chip from within.
I have always been concerned with regard to warranty work when thinking about chipping, dont know whether any of you do ( well i know Adam did ). The install is done via the serial port (from what i understand) so no messey soldering in the ECU, also the OEM chip is there so if a claim is made i pressume its undetectable!!! Now that has to be a bonus right!!
Well i thought i should share the joy!!
Heres the link to their website, looks like Forge are endorsing their products too!!
