Ask your tuner if they are commanding it to dump fuel as soon as you transition from vacuum to boost. Otherwise, there is no free ride with E85 and if you are running pump E85 and not testing it/adjusting the timing for the % that comes out of the pump...you are living on borrowed time. Pump "E85" can legally be between E51 and E97 since there are no E ratings between those.To answer some questions here:
This car is not running the factory turbo. Stock, these cars will dyno 160-180 at the wheels. Mine dynos 307 horsepower at the wheels. Right now I’m only limited by the factory fuel system. So yes, this car is very very tuned.
I know the injectors aren’t leaking because I would have other issues if I were. My AFR at wide open throttle is 11.5-11.7, no timing is being pulled, and the exhaust never smells like sunburned fuel even in a cold start. No smoke, nothing. There is a little soot on the tailpipe but nothing different from when the car was stock.
I did pull and reseal the injectors after that first sample was taken. I also had them serviced. No issues were found by the company I had do the service. I also replaced the evap purge valve and the charcoal canister. I only run top tier and I do not short trip the car. Monday through Friday it’s my daily and it does 70 miles a day round trip.
I know the fuel dilution is from the fuel I’m using and the fact I’ve almost doubled the factory HP. This car makes 26 pounds of boost at 3200 rpm and holds 22lbs to redline.
The main reason I was doing an analysis was just to recheck for dilution using the no VII oil.
