That is exactly the way its done!
Some use a dyno, some use DLL, some use the HP and TRQ calc in EVOscan, but most have switched to JackOfTrades Virtual Dyno.

Quick question for you guys, though. Are you using a tool like the Virtual Dyno to plot the hp/tq changes for successive pulls while you slowly ramp the timing up? From what I understand, it's pretty easy to get to MBT and past without any knock on E-85 and if you are going past MBT, then you are losing power and giving your bearings a beating, which can eventually lead to an engine failure.
Just curious about the methods that everyone is using. When I tune this week/weekend, I am going to go up about 1-2* at a time and plot each pull on the virtual dyno to see where MBT is, then back it down a bit.
For those who have found MBT or use this method, can you mention a few load/rpm/timing values for MBT for your setup?
