What does your weather look like tonight? Cough cough lol I cannot wait to see the difference on your vehicle between pump and higher octane. I'm really living vicariously through you. Are you going with 50/50 mix?
I totally Forgot to answer your 50/50 question. I'm sorry brother!!
I did a bit of math. My car holds 17.9 Gals. according to a site I searched.
I figure if the tank was full and I only use 5 Gals. of MS109 and the other 12.9 Gals. were 93, that'd give me an avg. of 97.5 octane.
So, depending on how much is in my tank now (I think It's quite full or close to it), I'll have to do some guess work to make it around 100 octane.
I don't want to use more than 5 gals. at a time of MS109. This stuff ain't cheap!!! lol
But would like to maximize my time with the Race Gas tune by making about a full tank of 100 (mixed).
Meaning, so I can drive it a bit and see how it acts under normal driving and playing together.
Run the tank down a bit just enjoying the car a bit, and then go make some 60-130 pulls when it's close to the level it was during my new Stage 2 pump gas tune was.
Hoping to make it as close a comparison as possible so we'll all have really good Info on this combo of Tunes / Exhaust on a 991.2TTS.
So with an 18 gallon tank, How about 1/4 tank 93 pump (approximately 4.5-5 gallons) and 5 gallon 109? That should yield roughly 100 Oct and it's half tank = less weight. Or 3/8 of a tank 93 pump and 5 gallons 109.

Well, like said, since my tank is close to full..I'd have to drive it a good bit and then pour in the 5 gals. of VP.
Was just trying to maximize my drive time on that tank. But keeping the weight down is probably best.
I just don't want it to be too much lighter than my other test. Rather is be a bit heavier or close to same.

Well dang. Didn't know that. So, having less in the tank of 93 with the 5 gals. of VP is seeming more likely now.
It sounds like you have a plan! Keep us posted.
Got my race gas tune sent today, and I’m going to try it out this weekend too. You and I and getting to compare fairly closely modded cars and that’s pretty fun too.
i went thru a stretch of filling my 997 with 109 .. regularly. it was over $300 a fill. i switched to e85 shortly thereafter.
lol. Yeah, I can't see me using this tune much at this kind of cost. And I'm still concerned about using E85 too for a couple reasons (poss. damage and needing some special calculation or system installed to figured blend).

Yup...tmrw evening should be fun
Same for you. Can't wait to see how our test results compare.

Thanks man! It’s been a lot of fun watching you mess with your new car... inspiring actually. Excitement like a kid at Christmas. Lots of fun and I’m happy for you.

Thanks man!! Yours as well. You have quite the experience with some awesomely fast cars, so I love hearing what you have to see too.
I'm just an "open book" about most things, especially all my car / vehicles / motorcycle Adventures.. lol.
Interesting. You have the BMC and the turbo inlets on me, but I have the Catless vs. you and our times are similar.
Looks like you had a very good DA though. Crazy how LOW to sea level you are though. You're at 63 ft on that run, and my best 6.37 (invalid due to -1.3% decline) was at 999 FT.
I'll have a very good DA tonight myself when I test my race tune w/ ms109...
