congrats enjoy the fun! Numbers are a bit low for a dyno jet plus methanol.
Mustang dyno I had 574/532 before I added methanol on 9-10psi using an ECS1500.
If it helps, I'm at 640/588 currently and have been that way for a year. I've yet to have a want to add any more power a year later. Maybe that's because I've realized any more power I won't be able to reliably put to the ground on a street car.
Man 640whp on a mustang dyno is very respectable! Ya, I can't see you putting down anymore on the street LOL! Unless you are roll racing.
Did you read that other thread with that guy dyno around 850 WHP just ran a mid 9 second run at 150 MPH with stock trans and stock bottom end ? I guess tune and keeping things cool is all these cars need. I was simply stunned to see his results at those power levels. Point being I think these stock trans can handle 700 WHP daily if tuned and driven right.
I did see that, very impressive-especially on the stock converter!
I'm definitely not worried about the engine holding up, I've seen some guys out here run crazy huge whp numbers on stock 5.3 bottom ends. Being that I'm barely over half the power of some of those guys, id imagine my engine should have no problem.
My concern is more about the transmission as those seem to be more of a mixed bag. Like you mentioned, the tune seems to be the make or break key to it. The guy who tuned my car has a really great reputation across all LS platforms out here, so I'm sure he did the best that he knows how with this trans tune.
I know before we get into the meat of summer that I really need to do some sort of external transmission cooler to keep to temps down. I've not been particularly happy with the temps during the summer especially if I happen to get stuck in an unpredictable traffic jam. We've already had a few very-near 90 degree days and we're not even out of February yet, lol.

Another update after round 2 of mods. Below are the changes from the first dyno run:
-3.8" pulley and belt swapped for a 3.6"
-50/50 boost juice changed to 100% Torco meth
-Swapped to ZR1 map sensor (about 8.5 psi on the new pulley)
-Stock rear wheels and tires swapped for Z06 wheels with 345 NT05R tires
-Retune
The car made 586whp / 537wtq, a pretty substantial improvement from last time.
Below is a pic of the chart, red is the run this time. Oddly enough, the weather was almost identical to the previous time I ran back in February.

That's definitely one of my favorite things about the car. Other than the extra sounds, its just like driving a stock ls3 under 2500 rpm- silky smooth and virtually stock gas mileage (I drive mostly highway so it just putts along at 1300 rpm or so).
I would put money on you starting new thread in under 6 months "how much more boost can run?" LOL... You can get used to it so quickly.
Turned out to be a pretty accurate assumption.
Actually it was the tires that pushed me to mod the engine more. The stock tires were rock hard and would spin from even highway speeds. That certainly kept the thrill up, but it wasn't particularly safe. With the NT05R, itll hook anywhere in 2nd, and will even hold 1st with the right setup if you ease into it right. So it was easier to get used to the power once all the drama was gone.
Are you running those tires on a narrow-body rear? If so, got any pics? I'm considering going with a widebody rear-end conversion in order to increase traction, but I would also consider wider wheels/tires on a narrow-body if possible.
Congrats. 525 WHP is a lot for regular C6 tires. If you can afford to get the widebody and Z06 tires in rear you will be blown away how much better the traction is. If not atleast get some really good tires. PSS hook very well.
Take this nonsense and toss it.
Good numbers. The A6 has been proven to go 8's, but the tune has to be spot on. I'd personally lean on it a tad more and leave it at 575-600rwhp
First pass. 11.2 on 19 inch skinny runcrap tires with just a base A&A kit. With a stick. Picked the car up, drove it a day, then put a blower on it. Ran strait to the track with it when I picked it up off work a few days later on a Friday. A6 and it would have been 10's. Went 10.5 with only 1 pass then booted off the track for no rollbar after I put drag radials on. If I had more than 3 passes with drag radials, I probably could have gone 10.1-10.2. Better tires are a great mod, but the gain on these cars is Compound and Height of the tire. Width doesn't mean much. Hard to replicate the driver mod on these cars even in an auto.

Yes, I ran them on the narrow body for a month or so. I bought a set of z06 wheels for super cheap from a guy that had them on a c7. I got then for super cheap so I couldn't pass it up - I figured even if I didn't use them, I could split up the wheels and tires and make some profit.
I couldn't use the size front tires he had on there as they were the same height as the rear, so I sold the front tires and swapped on my stock 245 front tires to the Z wheels to get the proper height stagger so the computer didn't freak out (fits great).
He already had fresh 345/30 nt05r on the rear with almost no mileage on them so I just ran them as is while I figured out what to do going forward. They hooked so well, I decided to get the rear widebody rather than change tires out. The 345 stuck out pretty far and looked terrible, but I just took it slow going over bumps and such and never had an issue. I'd say our roads are well above average though in Phoenix.
Below is a shot of how far the rears stuck out on the stock narrow body panels. Keep in mind the rear bolts are jacked all the way up to help keep the tires out of the fenders.

That's why I don't want to even bother with the drag strip. I was just out there last night and there were probably 5 cars running high 11s/ low 12s at 70 mph lol. Then they'd go and make one full pass and get booted. Talking to the one guy, they wouldn't even give him his time slip for his glory pass.
Plus if I read the rules right, I'd need a fire jacket to run at all with the aftermarket power adder. Just seems like a waste to me.
I am going to try some 1/2 mile stuff here in a couple weeks, so we'll see how that goes...
Yeah don't pay too much attention to those dyno numbers, with those times you are making some sick power! This just made me want to take mine to the track and get booted

LOL seriously ? a 345 tire will hook a whole hell of a lot better than a 295-305 .... Having owned lots of other high HP RWD LSx cars and my E55 with narrow tires. You are fooling yourself if you think widebody + tires wouldn't make OP much better to drive with that kind of power.
OP;
Nice numbers BTW for fairly low boost. I notice that even my 2300 is very stock like in lower RPM. My Maggie 112 was much more responsive in lower RPM than this blower. Of course I was running a lot more boost too. This thread reminds me I need to put my smaller pulley on ASAP.

Once you go wide you will never go back trust me. Look into the Supervette rear quarter panels. They make regular widebody look narrow.
Wondering if a converter, say in the 3200-3600 range would do for the OP's car?
Would love to do a converter at some point. The stock one is the lowest stall I can think of any car I've owned.
Seems like a bit of a pain for install labor though, especially since I don't have a lift. I know it can be done on jack stands, but looks like a tough job.

Lol, you seriously don't know what you are talking about. A 295 27.5-28" inch tire will outhook a 345 26" tire if they are the same compound.
I can post up 1.4 60 ft videos and slips on my base C6 M6 with the stock tranny/axles/rear end on 275-295 tires.
I have 345 drag radials on my C5 that makes ~900whp. Guess what tire I swap when I want to race? 295.
My street cruising 345 drag radials on the left, 295's on the right.
