Probably been covered a thousand times but Ima ask anyways since lot of the topics are 10 years old. The Stoich in my tune is 14.63. It's done, tune is where I want it. I know now that all gas around me is E10. Is it just simple to change Stoich in my tune to 14.13 or do I have to do VVE, MAF and PE all over again? Pros, Cons? Thanks all.
