FWD, AWD or Full Send ECU tune?

It's an S3, so awd.
I own a slow ass GTI, but don't R's run high 11's with stg 1 tunes? I'd think the S3 would be similar.

Duh.
Depending on box code and software there can be 3 different ECU tunes per fuel. Full Send is supposed to allow boost to be built on launch.
An A3 owner has run multiple 11.5-11.6 @ 117-118 mph passes on the Full Send map. I'm trying to gain more data points.
From what I've seen DSG R's stg 1 typically run 12.1-12-2, stg 2 11.8-11.9. Obviously a few run quicker but they seem to be more of the exception rather than the norm.
A local guy was at the strip with an R last time I went and he was clicking of 11.8 - 11.9, run after run, in 90 deg Florida weather. Maybe because it was a prepped surface.
Same day, I was running 13.7 -13.9 stg 1 GTI with stock intercooler.

From my research that is more inline with a stg 2 time. Are you sure the R only had a stg 1 91 or 93 octane ECU and TCU tune? Definitely no downpipe, extra sticky tires, weight reduction, and/or added ethanol/ethanol stg 1 tune?
Pretty respectable time! I'm not very familiar though with the GTI quarter mile times other than I know that is a lot quicker than stock.

The only golf r time I know is someone I follow who did a 12 flat at 112 on stage 1 e80 ie true flex. Intake, hpfp, intercooler

They don’t have a full send file for my S3. Just basic 93 AWD, then HPFP and LPFP upgrade, then HPFP / LPFP / MPI. Only a3’s 2017 and up got a full send file I guess
I just did a 11.5 index the other day for import faceoff. Originally I was going to run in the force induction sport but whatever firmware update happened with the cobb software has totally screwed my e30 tune. Basically anytime I launch the car with my e30 tune it stalls going into 2nd. If I use my 93oct tune Im able to launch. I did do a 11.4 @ 119 during qualification rounds. That was launching lower than I usually would and a slight let off at the end of the track.
The car def has 11.1-11.3 in it with a full send and cool temps on 93oct. That being said the e30 tune runs 6* more timing so shes going to be a 10 second car once cobb solves that issue.
I ended up making it into the final 4. All runs im letting off at the end to try and get close to 11.5

Is your S3 6 or 7 speed?
FWIW Arin mentioned if Full Send isn't available a request can be put in for your ECU and software.

6spd. 2016. I’m an audI tech and APR dealer, I sent through a ticket for a full send file weeks ago but nothing to avail.
I have no specific knowledge of the car, only what the guy said. He's a VW tech, part of our local club, had just purchased the car and said it was stg 1. He had to borrow my helmet after his first run, because track requires one for less than 13 sec and he knocked off a ln 11.9 first run and got the stink eye from folks in the staging line.
Stg 2 GTI's DSG were running 12.5's.
I did have the advantage of 255 200tw tires too.
Here's a DTR review from someone who was banned from the forums. They went from an APR stg 1 low tq tune to the DTR on a 7.5 GTI. Everything after this is not my own words:
Mods: DTR turbo swap with apr tune and apr tcu tune (FWD version, because Jesus Christ of course one should pick that in a GTI) AWE track cat back, IE intake, heat range 9 plugs (forgot which ones), neuspeed wheels (dunno the model but its the one 80% of y’all have) and pilot sport 4s’s. and a dope ass fmic.
Received my DTR in mid March (I think) and had it installed in early April (I think). I was holding off on this review till I got my summers back on. Summer wheels and tires (PS4S) went on about first week of May. Ive driven enough on my crappy all seasons and on my summers finally. I think I am ready to share what I think of the turbo, since I am finally able to draw a conclusion.
Build quality of the turbo, outstanding. Especially the included hardware. The tune also doesn’t feel like it was put together by a high school kid. ECU and TCU tune were solid, as expected from APR. I was fortunate enough to come in later, after the early adopters did. No weird strange beta tune experiences.
In my daily drive, I do find myself giving the car maybe 5% more throttle? It’s so slight, I can barely feel I’m giving it more gas but I know I am. To be fair let’s say I’m giving it 5-10% more throttle then? There’s definitely some lag but it really feels as if it’s kinda like an is38. At wide open throttle, the car is making stage 1 type power, then around 3k rpm it feels like stage 2 power and from there on it is its own monster. 4th gear is incredibly fucked, its as if that might be the only gear that doesn’t have boost reductions or boost onset delays. 4th will get you into very illegal speeds very quickly. Imagine walking in onredacted (fuck U bitch) sucking his own dick, like that. That’s how shocking it is.
Gas mileage hasn’t changed. In the city and on the highway. Hasn’t gotten worse or better. It has stayed the same. Frankly I am neutral here. I went into this knowing I was going to lose some mpg, cuz bigger turbo and all that’s required to get to the speed limit. Yet, it didn’t swing that way. Cool.
The tcu tune on the 7 speed is solid as hell. Kicks down quickly, give it enough gas and she will down shift, all the usual stuff you expect. When driving up a steep hill, ill either stab the gas and hold 50-60% so the dsg kicks a gear down, or I’ll pull a paddle and just down shift.
The anti surge features make for this whistling noise and it take me back to when I had a supercharged ion redline. With my ie intake, it whistles loud as shit. I can put a diesel to shame. Folks walking on the side walk can hear it too. I really dig the sound. The part throttle whooshes are gone, but at wide open they make a return. I guess due to the larger hot side, my 7 speed’s dsg farts (still not as cool sounding as the 6 speed dsg’s) are louder and more pronounced.
What’s really cool but immature, when the oil hits 180f (according to lie o meter) I throw the dsg in sport and get a little more aggressive. Acceleration happens with maybe 1-3psi (according to the other lie o meter) and the whistling is crazy as fucking fuck. The drivers next to me seem to be looking for the Cummings truck too.
So how does it do on the street? Extremely well. It wasn’t till I absolutely murdered a stage 2 is38 swapped dsg GTI that I understood why the dtr is only compared to an is38 when it’s on e30. The is38 isn’t a great option, it really only has slightly better top end vs an is20. The R head must make better use of it, assuming that’s why a tuned stock turbo R can hold longer vs a GTI with a is38. Be for real, what do you think will happen between a dtr and is38 when both are on e30 or e50? I never understood why it was fair to compare the is38 on E vs the dtr on pump. Now I get it, it’s because the is38 sucks donkey dick and it’s barely an upgrade. Like I can do what you do but better and meet emissions and make cooler noises. God forbid I swap downpipes and get tuned or something.
Everyone talks about lag and it’s funny how it almost sounds like they know what they’re talking about. The lower rpm’s are only a thing when launching. And if launching, launch control barely gives you boost in lower gears. But I’m the middle and top, the dtr offers a good bit of meat there, where it would absolutely be usable
So who is this for? I’d say any GTI owner who needs to hold onto the stock downpipe due to emissions in their state. I wouldn’t on an R unless emissions was a thing and you’re also going to do the fuel upgrades. Otherwise I think it wouldn’t be a smart move for an R.
If Daks, no. Don’t get the dtr. Love U bro.
Many thanks to the homie Acadia for assisting me with this.

I haven't been in this thread in months or maybe at this point a year has passed since the initial thread start. After all said and done, it sounds like this would make a solid upgrade if your IS20 blows. Otherwise, in NJ and not caring so much about speeding like a nut anymore, I'm happy with the IS20 Stg1.
