2.8 remap to almost 3.7 prefl performance

[Ronin]

Once my car is mechanically sound I plan to get it remapped in 2022..
I've been looking around and not a lot of places are not able to offer anything for it but the two companies that I found can pretty much remap it to performance of the 230 3.7 prefl engine, only given whe the engine, gearbox and the rest are in good order.

What are your experiences/opinions on this?

I'm aware that If i wanted a faster car i could have gotten a V8 model but for me this is just an Icing on the Icing on the cake and I don't care that much for power in the A8, its all about the refinement. I would be running stock (quiet) exhaust, stock air filter and S8 wing mirrors (+8hp) or so I've heard
