JB4, DCI and 4.5g of e85 VDyno and Logs. Seem high, just right, help a noob

Hey guys so i didnt some pulls last night and logged them. That is the accurate Barometric pressure and correct temperature at the time.

One pic is with my weight, one without. As well as all my logs.

All I have is JB4 G5 ISO on Map 5, DCI BMS, with 4.5 gallons of e85 and the rest e10(Pump 93).

Do these numbers look right? inflated?

*log pic is of my last pull*

Changed it to Mustang Dyno and smoothing to 2.

That seems more realistic right?

Are the VD estimates to the wheels? If so, the “dynojet” version is way way off. A tune only car with some E85 in the tank is not going to make anything close to 450 wheel.

Yeah thats what I thought. Thats why I put it on Mustang Dyno, increased the smoothing, and that secondary numbers of 376/391 seem more accurate, I have tune AND intake as well as e85.

Thanks for the response. Any one else have any advice views etc..? How close is mustang dyno on VD to real mustang dyno? or is it closer to a dynojet in real life?

basically you need a perfectly flat road with no bumps and do many runs to get an idea of the power you might be making. Nothing replaces a good old fashion dyno though.

The Mustang numbers are in the ballpark.
