A4 stage 1 e85

[Calderone]

Is this normal? Just got stage 1 done and everything else is stock on the car. Not sure if the app is reading wrong but I converted it to 37lbs of boost at 90mph?? I thought it peaks at like 20lbs and holds around 16-18lbs. Any help is appreciated. This is the first tank of e85 in the car aswell. Thanks!!

if you read your graph you can see the flatline at atmosphere

Thanks! So how do I convert the mbar to psi? When I did it, I got 37

To convert Absolute pressure to gauge pressure take the value 2562, subtract 1000 mbar (air pressure at sealevel or 14.7 psi for a more correct number use the at idle reading as your correction number.) Multiply by 0.0145038.
