Switched over to E85 via OFT a couple weeks ago. No problems at first and major noticeable difference. On my 4th tank now and this week it starting not wanting to start in the mornings after she was sitting all night.

The first day it took a couple try's then the next day a few and now 5 days later it's taking 5-6 try's and making popping noises and stalling. Once it finally kicks over and fires up there are no issues. The rest of the day she fires on first try. It's just in the morning.

I've read that in cold weather the E85 tune can be hard to start but I'm in Socal and the weather was in the 70-80's when this started and we really haven't had any really cold weather.

I'm going to switch back to the stock tune for now since the popping is concerning along with the increasing amount of try's to get it to start.

I'm going to be installing a header next week and I'm wondering if I should have the car tuned on E85 at Church's?

Was really happy with the OFT E85 tune and don't really want to go back to 91oct but the hard starting doesn't seem healthy for the car.

What would you do?
