Flash tuning an Audi SQ5 twin turbo daily driver to 35PSI! Dyno, 0-60, 1/4mi of V6T 3.0T TDI

Gone are the days where diesels are sluggish truck engines. Bring in the age where a stock standard SUV can do the 0-60mph sprint in under 5 seconds..
We recently just picked up an Audi SQ5, which in true StreetFX style, needed some modifications right away :)
We chat to E-Tuners and see what kind of power and torque we can squeeze from the twin turbo V6 diesel 3.0 litre.
Many thanks to E-Tuners Brisbane for the tune and GT Auto Garage for the dyno time.

[@michaelrobinson1134]

Just found this. Thanks. I'm looking at one of these now. Love the diesel. Great times both 0-100 and 1/4 mile!

[@daveallsopp320]

First generation is definitely better than the second on many counts especially the lack of tail pipes and thdd ex awful interior

[@lukekilah6257]

My 2.0 tdi is running 37.5 psi of boost. It’s a little rocket ship. 497 nm as well. Don’t underestimate new generation Diesels. Especially if their remapped from a quality code writer

G’Day mate... just wanted to know how the car is going now 2 years later? Are you still running the tune, had any reliability issues? How many k’s has it done in the last 2 years ??? ... thanks Matt

[@moggie77077]

Love the torque from diesel, I'm pushing 45psi through our A5 3.0tdi, bigger single turbo and fuel pump made 240kw atw and 800nm of torque shocks a lot of people :)

[@lautarohunzicker]

What other mods did you have to do to support this new power figures? Also how does the transmission is holding? Are you able to maintain good consumption figures when cruising?

[@Crisytaisr]

New diesel’s love boost. My 2014 5-series M5-50D with tripple turbo’s are running 520hp/1050nm @ 55-58psi / 3.8-4.0 bar on all four wheels. Originally it’s boosting to 50psi / 3.5 bar and 380hp/740nm.

[@StreetFXofficial]

58psi?!? Are you sure that isn’t including atmospheric pressure of 14.7psi?

[@Crisytaisr]

Bmw says "Maximum boost pressure is 3.5 bar", when the engine is original with no tune. If I check the boost it starts at 0bar and stops at 3.8-4.0 at full pull. So I guess it’s 5bar with atmospheric pressure.

[@mikkinikki1902]

do you have an extra transmission in the back shed?

You can also completely disable the ASC/ESC etc. by holding the Traction Control button in for 5+ seconds. Same as engaging launch control. No need for fuse removal.....

[@rossisaacs541]

Great vid How much was the tuning ?

[@johnsnow5239]

It's a sequencial turbo setup. Basically a compound turbo setup. That's why it looks weird. The turbos are different sizes. One blows thru the other. Helps eliminate low down lag while at the same time having good topend power. Sure u knew that. Just wanted to get that off my chest. Lol.

[@StreetFXofficial]

I am actually not sure if they are twin or compound. I would expect compound to run far higher boost, but I will check on this and write back :)

[@jobhoogeboom]

@@StreetFXofficial i think they are compound turbo's. german diesels always have quite small turbo's so there isn't a lot of turbo lag, and for emission shit..

[@StreetFXofficial]

The turbos on this are quite large - if you have a look at the engine bay clip in our video. Probably somewhere close to a GT30 size.

[@alps4391]

I’ve got an sq5 used as the family wagon, the cars equipped with Audi drive select how does this work with that system?

[@StreetFXofficial]

Drive select doesn’t really do a lot aside from change simulated exhaust noise, gear changes, steering and throttle response. Just changed driver experience but ecu tune doesn’t really change those individual settings. It still has all the different modes.

[@reeceglasby4080]

[@DarrenC81]

I’m seriously considering buying a used SQ5. Anywhere from 2014-2016 with as lower KMs as possible. Can anyone answer these questions. 1. Any major problems, aside from general issues associated with age. 2. What other mods aside from the reflash are recommended. Keeping in mind I want to maintain longevity of the vehicle. 3. Do E-tuners still exist and what other tuning/performance workshops are recommended?

[@mangoburger7999]

I got a low km 2013, love that they don't have adblue. Previous owner flashed it 390hp 933Nm. The 8sp trans is better than the DSG in the Q5, they are known to fail often and happened to a mate, exy. The only mod it has is the software upgrade but it has some nice factory options. Don't really need it to go any faster. 20" rims are less jarring than the 21s. They chew out the back rotors if you drive on radar cruise. MPC(Vic) did the tune

[@KentisMentis]

[@doublevfx]

U know that u can make it go even faster then that time with specific rpm gearshift.. try to gear at 4k next time and see what happens

[@StreetFXofficial]

If you set the launch control rpm too high it will trigger fault codes and limp home. I think 3100 is high enough to be between performance and base.

[@doublevfx]

@@StreetFXofficial I don`t say that u should launch at 4k. your launch rpm is good.. But when the car switch gears u should make it shift at 4k rpm so u get the most out of it. cause diesels drop power after 4k

[@StreetFXofficial]

Ah understood. I think since it's making power til up to nearly 5k, if you shifted too much lower it will drop out of its power band.

[@doublevfx]

@@StreetFXofficial if u take a look on the diagram of the engine with the tune u got then u will see when is making power and when it drops power. it is different on all diesels. but u should look at the diagram to see when is making all the power to make sure u get every single horsepower :) im not saying this to hate or anything.. Just to help u get better 0-60mph

Pretty cool. 35psi is taking it real easy though, I have my shitty 3.0 4cyl diesel hilux at 40psi with a big single turbo, been running that for 4 years. It makes 205RWKW but 900nm of torque. The diesel pump is maxed out though so that takes my top end away, a new pump should get me to 250rwkw. Looking at getting an SQ5 for my wife, I will be pushing as much boost as the turbos will give.

[@damaged31]

Nice vid. What’s the launch control technique?

[@StreetFXofficial]

Dynamic mode, esc off, manual shift mode, brake on hard, accelerator flat to floor. Wait for revs to build. Release brake. :)

[@damaged31]

Awesome - will give that a go 👍🏼

[@kobie451]

@@damaged31 Just dont hold the car to long in that launch mode as it is not good for the clutches i heard.

[@grw1618]

So your manual shifting on the paddles? I just put my foot down but I need to learn to 'wind it up; like that...Your saying put it in dynamic, esc off, manual shift mode, brake on hard, accelerator flat to the floor, and it will wind up and stop at a set rpm? then just take foot off brake and enjoy? :) Also will it do to full auto mode not manual once it hits the rev limiter on 1st gear takeoff? thanks!

[@bigbaIIs]

@@grw1618 the above process desribes the Audi Launch control, as long as it's in dynamic or S mode you can leave it in Auto shift also. However you also need to ensure the car is up to standard operating temp. with your foot hard on the brakes put the accelerator on the floor and the revs will build and hold for a few seconds. Release brake. Goodbye

[@amirst110]

100-200 kmh?

[@StreetFXofficial]

I wouldn't expect it to be hugely fast at the top end above 180kph as it's quite a large vehicle. The 0-120 is great, after that it's a bit slow.

[@iangelxD]

[@typ930]

33 psi stock??? damn!!! is it because it is a diesel??

[@StreetFXofficial]

Yep.. Also a lot of factory cars these days are running crazy boost. Even petrol AMG A45's run something like 26psi to make the power they do from a 2.0L. Crazy times!

@@StreetFXofficial i am aware of the a45, but this thing has an extra 7psi! did not know diesels could stand such pressure factory stock!

[@StreetFXofficial]

It had me baffled as well when I saw the readout 😳 I had to calculate it three times to be sure. Diesel blocks are far stronger due to the way they use compression to ignite, but they have certainly come a long way for making them good for every day, economic and powerful applications.

I considered the lx570 as it was the same price as the sq5, but after I drove the Audi I was impressed with its acceleration so just bought it. Already have a prado if I need an off road 4x4. We did get the v12 TDI Q7 but only the older model, and they’re much slower than the current v8 TDI SQ7. Even the SQ5 is faster than the v12. Unsure why they didn’t wind them up more.

Can be flashed back to stock.

Either way, if you main concern is warranty, then wait til it’s out before you chase more power. Our Audi is just out of warranty so it makes no difference to that anyway.
