When MHD releases v3.61 of the app later this week, I'll reflash to fix my disabled CEL issue.

I’m planning on flashing these 4 options in the multi-map slots:

1: Stg2/91oct. 100% (daily driver)
2: Stg2/91oct. 60% (valet)
3: Stg2/93oct. 100% (max fun on pump gas)
4: Stg2/93oct. ??% (HP/TQ between the Stg2 91 and 93 oct. maps)

Question: What % should I use for slot 4 to get an estimated HP/TQ rating that is in the middle between the Stg2 91 and 93 oct. maps? 90%? 95%? Some other %?
If I knew the estimated crank HP/TQ ratings of the Stg2 91 & 93 oct. maps, I could figure it out myself, but I haven’t been able to find those. Anyone know what those are?
Thanks for your input!

p.s. I asked MHD this same question and their response was one line: "you have to try what works best for you."
I understand their reluctance to provide HP/TQ estimates, but that response wasn't very helpful.

Edit: Thanks to Skyhigh's bump of this thread, I found this comment from MHD: "on 98 (93oct) you can expect around 390 ST1 and 420 WHP ST2"

So, if I put Stg2/93oct. 95% in slot 4, that should give me a map that is somewhere between the Stg2/91oct and 93oct OTS maps.
