EPL OR APR STAGE 1??

[15 Phantom S6]

Chipwerke not even comparable, right? I’ve considered them too mainly because of the cost.

Claims to add 35% more HP and 25% more Torque for $450. Seems too good to be true.

Not comparable to a real flashed tune but it definitely adds alot of HP. I wouldn't be surprised if the percentages you posted are accurate. I had one for my B8.5 S4 and it added a shit ton of power, probably between 60-80hp easy.

Also, I don't see anyone mentioning Unitronics. They have a comparable tune, you can flash at home and its a touch cheaper.. On top of that, they claim more power than the other tuners as well (for stage 3 at least)..

Unitronics is a great shop, they did a custom tune for me about 8-10 years ago for my BT Audi TT and I'm still using it to this day without issue..

I guess I'm in the minority of folks in this thread, I had EPL stage 1 for my 15 S6 and I had no issues.. I was also a happy camper to be able to sell it and get some $$ back when I went to stage 3..
