Lost performance

Agree with FoMoCo... But I will say that my car didn't seem to like the new Shell Nitro Plus... So I am back to Chevron and happy again.

My car loves it.

I have a data logged run where the car decided enrichment wasn't for her....needless to say she ran at some pretty high WOT AFR's but didn't knock. I'm sure the corn and ACES had much to do with that but if my base fuel was crap I suppose my results could have been much different.

i might just switch back to my E20 tune. the gas station with E85 is much busier so the 91 should have a higher turn over. it is 100% gasoline philips 66 brand
