at 3600lbs your going to need over 750+rwhp to go mid 9s well over 800 at the crank,more with higher elevation.boost is just a number.
Looking for mid nines

My car weighed 3535 lbs with me in it. Brian Cotton (my buddy who drove it) weighs about 25 lbs more than I do. This put the car at a race weight of about 3560 lbs.
With low boost, low timing, and a high 1.5 60 foot time, the car ran a 9.67 @ 145.31.
At a higher elevation, you may need 2 lbs of boost more than you normally would need at sea level. But I don't believe it should be a problem.
It seems you have everything you need. But like anything else with these cars, it's a process.
To share my very limited experience with my car only. I like to think that I just went to the track and ran the number smooth as butter. And that day we did! But, I had the parts in place to do it for years earlier. I just never had everything really debugged and worked out. Even that day, the tires were 3 years old and dried out. The launches sucked, there was no 2 step installed yet, and I wanted to keep it mild for the 200 mile drive back home.
If your tune is set up for a 9 second pass on E-85 already, it shouldn't be too hard to first convert it over to 93 octane fueling and timing. Then do the VE reduction for fuel replacement for the alky. Then do the individual injector corrections if even distribution needs to be addressed. Then through the alky timing in at the areas where it comes into the map. The more you can get it close on the street, the less time you will waste at the track.
Drive it! It's the only way to find and work out the bugs before they surprise you.

I think around 28# boost. A friend also has a 274 stage 2 very similar to Roberts with 71gtq 4 bolt. Has alky, but hasn't leaned on the alky much. Race gas and 23-24# went9.54@145with very easy 1.6 60ft. Went 117.5 mph in the 1/8.
It was about 3800lbs with a stock location intercooler. He's looking to drop a few tenths with a front mount and more boost.

My experience at elevation (Bandimere -> Bradenton), I could trap about the same with the same boost (hair faster at sea level) but took a lot longer to spool up at altitude.

Yes, the intercooler is all installed. I believe the race n/l trans is back in too.
I've seen the same though it's only been 2000-3000" vs sea level comparison. It doesn't really matter much unless you are close to all in with the turbo. If all in the air can make quite a bit of difference. Tune spot on for both. 330' time better at the sea level track.
Ok this is what I'm doing Cal is going to tune my car on the Dyno. He is going to do 2 tunes. 1 for alky on 93 not sure on boost maybe a little input from my fellow Buick friends on that.2 e85 again a little input from my fellow Buick friends on that .wonder what the difference is going to be if based on the same boost level and it's actually not E85 it's e98 my friend is a vendor who has the dyno he wants to see the difference on my car and my car is already set up for E85 .but regardless I'm pretty sure 99 percent of the time I will be doing alky

To get mid 9s your not going to need to turn it up to high. Talk to cal and he will dial you into 9sec power. You guys can see what it's making on the dyno and determine when you want to stop. You can go to 30 psi on both setups but is it needed for your setup. No imop..
