I've got a 207cc and have been pleased with it for a couple of months. The THP 150 engine was initially quite powerful given it's only a 1.6 and the boost threshold was about 1500rpm. From there on up the power was pretty much linear.
Now though after a new months I've noticed a flat spot between 2000 and
3000 rpm - this happens on occasions, usually when you've just pulled out onto a roundabout!I did a little googling and there are some mentions of this on both the 150 and the 175 bhp THP engines, and also being experienced with the same engine in the BMW mini, so my problem isn't unique. There is some suggestion the engine mapping is storing invalid values and the problem goes away if the garage reset the stored values.
One guy has had his car in 7 times with various bits changed with no change, I wondered if anyone here has any more info? I don't particularly want unecessary time spent in the garage randomly changing bits. The salesman knew nothing of these problems when I asked last week.
Cheers, Dave
