Hi there, thanks for sharing this, we did actually a few tests on the bench at EMS Motorsport in Paris. The reality of the power gain with only a bigger air intake and larger exhaust pipe,  fitting a competition filter or not is minimal, as is the gain from a greater gas outlet = 5hp in most cases (for gaz  outlet it doesn't even change anything). Therefore there's no real interest if we compare the net power gain (especially with a turbo) on certain vehicles by simply reprogramming the stoichiometric engine management (10 to 20% ). The power/price gain ratio on engine parts only justifie when there's a need to increase more than 50% from its original power, or more... Also the 4 cylinder 20V 1,8lt has limited connecting rods and will brake if you go over 420Nm this might be a limit on the choice of the kind of stage you swap the car without having to change the original rods and much more.  A bad example not to follow is that of Humblemecanics where even with a big turbo it does not exceed 200hp - (I think it was a 180ch TT and guess he didn't reprogrammed it)  other wise there are also many other very successful swap on the TT but what we see most often is the replacement of the intercooler which again is absolutely ineffective below 300hp just like replacing the air intake or  the exhaust line. All these modifications are only justified from 300hp. Below that, a good reprogramming allows a TT quattro of 225hp to easily pass the 250hp bar as long as you provide it with the quantity of gasoline (i.e. respectively 400cc/min for 225hp or 450cc/min for 250hp) translate in US gallon per hour (38,67lb/h for 225hp). Another good thing to do at first is to install a pedal box and a quick shifter, those give without any other changes allready a total different driving feeling.  Cheers from Geneva Switzerland

Dom, you have certainly made my understanding of remapping clearer and now I know what I need to do for stage 1, stage 2 and stage 3 if wanted to take it that far.  Keep up the great work you are doing :)

Nice one Dom, remapping made clear. I think a soft ware map is for me, l am quite fond of my clutch !!  Was good to see you on Sunday.✌️

If you change the map change the gap on your plugs as well.

Fabulous video Dom! Lots of great info there that seems to get asked on the various FB groups. Top drawer as always!

Awesome video man, literally just crossed my mind as getting close to mapping sometime early next year :D

I had mine done a couple of years back after fitting a cat back scorpion system & RamAir induction. It was down a bit to start, 194 at the flywheel but it came out at 251 and the driveability was great. Well mannered in traffic and a much nicer shove when on boost. I've just changed all the charge pipework for Forge electric blue ones and the heat shield you recommended arrived from David Clarke too with my ProRam filter. It looks great under the bonnet now. I did the interior clean & seat delete in the summer so winter will be cleaning the underside with braded brake & fuel lines. I'm really down the rabbit hole with this one 😂 😂

Just bought mine, 225 Quattro on 109k miles, proper looked after with servicing etc, loving the stock power but looking at mapping in the new year… this is highly informative, THE best TT channel on YouTube in my opinion… thank you Parrott Bro’s😎

This is super useful. Thanks!

Great video dom 👌

thank you for the vid

I like this video, If I should have  my 225 done early year will be referring to this

Great video Dom. I will do the stage 1 map from swedish BSR later. It gives +47hp and a extra 118nm of torque on a BAM engine. Looking forward to this upgrade

Useful video dom got my clutch and pipewerx downpipe fitted and AP coilovers front mount intercooler next then another remap

Great vid again Dom 👍 Thought I'd leave a comment to see if anyone has remapped a 3.2 MK1 TT... Obviously being non turbo, you only gain 20-25 bhp/torque so wondering if it's even worth it/you notice the difference 😊

Great info . Just had mine mapped and it made the clutch slip . Have you any advise on a replacement for a MK1 225

Thanks for the great recommendations. What would be the stock psi for the 180 and 225 motors?

As always, useful and the the point. But could you recommend someone in Kent, want to do a whole load to my TT but I’m not mechanically minded- there’s got to be some good guys in Kent that can do stuff?

Hi, thanks a lot for your videos 😉
What do you think about e85 fuel ?

Hello I have my Audi TT remapped stage 1 by Rhino it’s quite a while now as asks for the receipt and I was told He is going to send me by email,but never received any email . So I have no Idea how much power my car gain.and if I changed to down pipe do i need  still to remapped my car . I got militic exhaust. and planning to install an inter cooling.
