1.8bar 725whp virtualdyno; 830hp dyno; supeflow800; lower timing tune
2+bar 704whp !!!! vdyno; 916hp superflow800; higher timing tune

the last setting was used to break 4s 60-130mph


I guess because of the MAP sensor limitation the vdyno can not show real hp for higher boost than 1.55bar unfortunately... this should be the case for Todd's car too, I would be curious to see, but I am quite sure the result will be lowered a lot as the app thinks we run only 1.55bar tops

I will try later to add manually the correct boost into the csv file and see how the results will change

There are many variables you could have configured incorrectly that scew the numbers!

Boost makes no difference in the calculation. It only uses RPM and TIME. The only reason the program reads boost is to graph it.
