Surpassed my expectations!
And then I ran out of injector and then I called it quit. Also It didn't want to enrichen when I comanded more fuel. Like the pump was giving up or the filter is plugged.
I can work on making that torque line flatter.
Some notes:
It gained about 60lbs/ft of torque @ 3000RPM and about 50lbs/ft of torque @ 6000RPM compared to the previous dyno!
304WHP@6000RPM
309WTQ@5000RPM
Overall I'm pretty happy with the results!

Thanks Spades! I was able to squeeze about 60lbs/lbs of torque@3000rpm but my surprise came at the top end. It picked up about another
50lbs/ft of torque @6000rpms! The torque curve looks like an eletric motor torque curve!

...and on a MUSTANG dyno which means you are really making over 330 rwhp most likely...
Amazing, yet to me - completely unsurprising - results! I expected this and if you went back to stock wheels and tires it would be a bit higher.
E85 adds power across the board and likes compression. I picked up 12 hp with barely any tuning. We couldn't get an A/F reading because I had too many holes in my exhaust...
Actually, I need to go back to the dyno at some point and perhaps I'll put on some street wheels to see what I'm really making compared to my 52 pound wheel-tire combination.
Perhaps you can add a signature to your posts that says:

 That's not a bad idea!
I went to the ThirdGen forum because a guy invited me to share my results on the 3.4 and let me tell you about trolls!
One dude even said that he wants to see the car run on the quarter mile to see if it matches the hp I'm claiming because he doesnt believe me!
And he says so because he has seen lots of people try to hit 250 with aluminum heads and more stuff done to the engines than what done and because "I now these engines VERY well".

Your chart cuts off at 5500 RPM?
Do you have the full one that goes to 6000 or more?

It was difficult to keep the RPMs steady at 5000 when trying to match the car's tach to the dyno.
The smallest variation of the throttle caused a major RPM climb so we did our best.
I believe I let off at 6200 looking at the car's tach. We also set 6000 for max rpms.

At what point was the prior dyno taken? You've done more with it than just the switch to E85, right?

I could swear I saw something over the summer where he was at ~277 rw [MustangDyno] HP...and I commented that that is 300+ on a dynojet already...and that was pre-E85...
This was not long after posting my +10-12 rwhp gain just by switching to E85 with a meh tune...and gaining 22 rwhp @ 6000 rpm by "fixing" the Fiero middle intake manifold...[This message has been edited by lou_dias (edited 12-17-2019).]
