Hey guys don't laugh, this is very possible. I know I've had 3 FSTs and have on occasion had a play with the odd CTR EP3. You need to realise a few facts here..
A remapped ST to 270bhp, well actually if its "just" a remap its about 260bhp and as soon as you start to hoon it you loose 20bhp of that as the s
tty stock intercooler can't cope.
The standard ST suspension and its weight means unless we are talking straight line the CTR has a an advantage.
On the twisties I am willing to bet the remap actually slowed the ST down. The low torque CTR if its driven correctly can get all its power down and get max power to grip in the bends. The remap on the ST will make this pretty much impossible. Way too much low down torque and most the remaps have aggressive boost strategies.
Also as already mentioned the ST turbo can't hold full boost at high RPM unless the downpipe/cat has been sorted.
So in summary. Lazy everyday driving/drag strip jobs - ST. Twisties/Handling - EP3 CTR no contest.
Anyway if you had read the guys post you will see it apparently had the fmic and full exhaust system as well as the remap.
On twisty roads the power difference would be less obvious and driver skill comes into it massively, but then a well driven underpowered car in this scenario could stay with a poorly driven massively powerful car. This scenario was not suggested to be the case by the poster.
In a straight line a standard ST is a little quicker as the speeds increase, but a modified 270bhp one is another story.
I also disagree with your last sentence but then that is a subjective point.
He never mentioned around the twisties just that he was suprised a 270bhp car was no quicker than a 197bhp car which is obviously not right.
