It's usually closer to 100 than 90 at our pump, RS Fuels on Memorial Rd near Portland in OKC. I've pumped from four different places, two are the same chain and the other two were different. Apparently, up until recently since I haven't filled up, all were about 82% per my ECA. I don't have a E98/100/whatever tune.
I'm so happy we have good fuel distributors and I love my ECA.
Now, about this car and its power... So interested!
