I suspected as much, thanks for your replies. I'll save the money for something more important.
I use V-Power all the time and there is a noticeable difference if I have to use another brand, and even then I'll only put enough of that in to get me to the next Shell station. Tesco do a 99 but the flake keeps clogging up the fuel filter.

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. https://www.youtube.com/watch?v=3n7xVwjWWD0 The other way to 'power' is actually to reduce weight. Acceleration = Force (torque) / mass Last edited by Goran; 24th February 2015 at 06:58 AM.

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.

My usual Shell outlet (Chiswell Green, just off M25 J21A) was closed when I passed it on Sunday.
Had to fill up with BP 97 on the A12 near Gants Hill. The S8 looked seriously out of place among the chavmobiles..... (That's what happens when your younger son decides he's going to marry an Essex girl and live in her "manor")

Very droll about the flake.......
Where this would be worthwhile is for anybody on LPG as you can remap to regain the loss that running this on a normal advance curve gives you. Yes Will, this does mean you!

Thought I'd chip in on this one. Against the prevailing opinion I am completely in favour of remapping the D2 S8.
Along with a few others here I had the REVO Stage 2 map put on my old car. It was totally worth it in my opinion as it made the car far more drive-able in normal conditions and gave it a more urgent top end. The biggest difference was that is moved the torque further down the rev range. Before the map, the car really needed 4000rpm, before you would start to feel the push in the back. After the map, my car would pull from 2500rpm and then above 4000rpm it would start to stomp on again, with the final 6-7000rpm range being awesome. In fact it would rev out so hard and fast in the lower gears, the change up points where about 250rpm higher. In daily driving the car felt much smoother, even though I had the most aggressive map for the throttle response. It was faster at Santa Pod, I gained 0.2 secs in the qtr mile. Overall well worth the money I paid for it. The REVO map, felt entirely consistent on all the other cars I drove. In a side by side rolling test, two S8's with the maps couldn't be separated between 50-130mph. An added bonus for me was that when I forced to fit Sports Cats to my car, the map had already coded out the rear lambda sensors. Oh, it also removed the speed limiter, I had a GPS verified 158mph in Germany and it was still pulling when I had to slow for traffic.

The previous owner said he had reached 170mph in Germany, though I suspect that was indicated rather than verifiable.
