You quoted me then didn't?
I was 100% behind stever750's comment -
"The only way to tell that you're at the limit of grip is the sound of screeching tyres, as the balance and steering won't give you any clues. FWIW, I've been thinking about remapping my 245, but frankly can't be bothered, the thrill of just acceleration in a straight line soon wears off, and all you are left with is a paranoia of premature engine failure."
I don't claim to be the most experienced driver on Briskoda but have owned or driven cars with over 400 bhp and many years ago motorbikes that could crack 6 seconds 0-60. Just because I draw a pension doesn't mean I'm senile.
In a wider context (been there, done that) if the car you have isn't powerful/fast enough then don't waste money on tuning, just get a different car. (Or a more powerful model in the same range.) Fine if all you want to do is see what you can achieve, but in the end unless you're throwing over a ££grand at it then your money's better spent elsewhere. One learns as one grows older that purely for road use and within legal driving parameters then the set-up by manufacturers will invariably be better than whatever the amateur tuner (that's the end user, not the tuning company) thinks they can achieve. It's taken me decades to acknowledge that you don't need to have several hundred bhp, or torques, as Clarkson says, to enjoy driving legally fast on public roads. And here I mean minor A and major B roads not motorways etc.
At one time we had a Citroen AX, 1100cc, 60 bhp, and a Peugeot 1.9 309GTi (widely regarded as the best, if not prettiest, of that generation of fast Peugeots) with more than twice the power at a heady 130 bhp. There were many times when I preferred the Citroen to the 309. Both could manage the back roads of north Wales and the likes of the Snake Pass between Glossop and Sheffield at illegal speeds, but when discretion was needed in some of the more challenging stretches then the Citroen was much the better car. The pleasure and skills needed when driving a car at ten tenths were and are far more rewarding and demanding than driving a car at six or seven tenths along the same road. And that holds true today, when the 130 bhp of the 309 is regarded as an average output for a family hatchback. The current comparison still holds true - we have a 75 bhp VW Up, and a 150 BHp Karoq. The Up is usually far more enjoyable over the same roads, for the same reasons. And also when compared to my previous Octavia vRS over the same roads.
I agree, a surfeit of BHP comes in handy when joining motorways and some idiot thinks 35 mph is the appropriate speed to join traffic travelling at twice that, but generally for the better than average driver (isn't that all of us?) the ability to use what you've got is more important than what you've actually got.
I write as someone who since the millennium had 220 bhp (and more) to use every day but for the past year just 150 bhp, and while it took some months to adjust I really don't feel the need now for the extra power. My enjoyment is seeing what I can do with what I've got.
On a slightly separate note, If someone wants to drive at really high speeds then there are plenty of private racetracks for that, many offering "track days". Youtube's full of videos of people wrecking their pride and joy at the Nurburgring. At least there, they're only risking their necks rather than those of innocent road users
