Hello.! I have a C7 Z51 from 2015. It has a downpipe (no cat). Xpipe (not cat). and KN replacement filter.
I use 98 Octane unleaded gasoline.
In Spain it is the best there is, I think it is equivalent to the 93rd in the US.
I have an HP tuner and I have already done some things... but...
The truth is that I don't dare to make a good tune...
Could someone share a tested Stage1 with me? For my car, something without risk of breakage?
I attach my original file.
I hope I can learn to do it for myself. but while I would like to enjoy...
I'm sorry for my English. I am from Spain.ecu ORI.hpt
