Hi, that's my first post and I'd like to share my tune from my A4. The file is for the stock car with K03 turbo. A month ago I swapped in a hybrid K04 with supporting hardware mods and all I need now is a new tune. The problem is I can't open the file in WinOLS - it says the file has already been modified - so I don't even have a chance to see what has been already done.

Can anyone here have a look and let me know what they think? I also don't know if I have to bother editing the current tune or should I start from the original stock file (which I don't have). Or should I leave it like that, since I know the new turbo isn't that much different and I'm not sure if could squeeze some more HP from it?

Thanks in advance

Current tune

If there's anybody interested here are the compressor maps for the stock K03 turbo, and two K04 turbos - my hybrid one should be closer to the K04-2275: Stock K03 compressor map, K04-2078compressor map, K04-2275 compressor map

Did you resolve your problem?
