D2 S8 Remap - worth it or not?

[brasiliangringo]

I spoke to a respected mapper on the Audi circuit when i had mine (Rick @ Unicorn) and he opined he could but wouldn't bother as the gains will be so marginal, i probably wouldn't notice it / be worth the outlay.

User - A8 Doc - on this forum used to be involved in remapping, no idea if he still does but worth a quick email I'd think

I doubt you could get 20hp extra without changing the exhaust. The stock S8 has 400cpi cats, and baffled mid and rear box probably not optimal for performance.
So before re-mapping you would definitely need to change the exhaust and cats.
To get a even a bit more power you would probably need to port & polish the intake manifold and get some long tube headers made up (very expensive). Then a remap after all the physical changes. Have a look at JHM S4 videos on youtube, they got a lot of power out of their S4, it has more or less the same engine as the S8.

The other way to 'power' is actually to reduce weight. Acceleration = Force (torque) / mass

Mine was remapped before I bought it. The graphs that came with it show about 5-10 BHP increase at best, although I do think it picks up a little better at lower revs than my previous S8, but you'd probably not notice the difference unless you'd been told.
