First tank OFT E85 tuning. Noise?

[Tromatic]

Stock car, approx. 50 miles on E85, 1.42 Stage 2 EL E85 tune. I'm aware of the ~4k intake snort, but does anything else change? The 4k snort seems to be a it less than the gas tune, too. I was expecting louder crickets, but so far nada. I know it's early, and I'm uisng Uplon fuel lube as well. There is also far less injector noise at idle, and it now idles like buttah.

Great fun!

The noise around 4k will be less on E85 tune than the petrol tune as the VVT/ AVCS is different for the tunes on stock car. E85 tune assumes you have headers so VVT AVCS is less aggressive.

Try the 1.55 E85 tune

I never get crickets on e85. I definitely get them on gas during hotter times of year/after driving hard. The car does idle smoother and the motor feels more refined on e85.
