Question BM3 e30 tune

I run stage 2 e30 tune and I was wondering if anyone was having issues with fuel lines. Do you guys recommend replacing them for aftermarket? I read that I should run 93 through it from time to time. Do I need to change the map to stage 2 93 map when I do?

I'll attempt to answer, but don't quote me 100%. There are smarter people on here than me...
1. Fuel lines should be fine with e30 or e85. Only old cars have trouble with high ethanol content fuels. Modern vehicles are fine.
2. If you have a 93 oct map, you should switch to it. You can run through a whole tank of 93 on the e30 tune, but you wouldn't want to beat on it and basically baby it for that whole tank, and what fun is that?
