Measuring blocks 32 and 33. For target numbers, it can be all over the place. I see 7-8% frequently in mine and it's fine, however if you see 10% or above IMHO, you may want to look into it. However with certain intakes, it can show 15-20% for the fuel trim.

This is for the Golf R specifically, but this is still valid if any other GTI owners want to give it a read as well: http://forums.vwvortex.com/showthrea...el-Trim-Issues

Lol, I learned a lot after testing for almost a year but now on the big turbo setup I have, I am adding a 5th port injector to run even more E85.

Ah ok. I've run those before I think it was under 10. I had fuel trims corrected for my intake when I initially got the tune.

How much E85 can our fuel pumps handle? Can we run straight e85?

I think its more a limitation of injectors rather than pump. I know some guys running UM flex fuel kit are saying e50 is about the limit
