yeah had the car remapped on saturday 189bhp 310lbft really noticeable difference.car and clutch done 73k to the best off my knowledge.
what seems to be happening is doing about 40mph in3rd gear about 3000rpm engine losses power then seems to kick in after few seconds?almost like theres abit off turbo lag, does this sound like it could be the clutch sliping? thanks for any advice.
If it seems to lose power but the revs are not rising then the clutch isn't slipping.
If the acceleration tails off yet the revs continue to rise savagely then it is the clutch slipping. You'd notice this very quickly - the revs would rise to nearly 5000rpm and the car would gradually catch up with it. This would be accompanied by some smoke and a horrible smell of what is basically burning clutch linings. If this isn't what's happening then read on:
When an ECU is remapped via the OBD2 port the first time it's switched on it reverts to the (new, remapped) base settings for fuel dwell, timing, duration etc. Also the boost control system will revert to the new base settings.
Over time the ECU 'learns', for want of a better word, its place in life and creates overlay tables for fuel and boost controls according to the input data provided in real time by the car, whilst being driven. This is the same as the car does right from the production line. Just that you've started this process again after a remap. It's quite normal. This is one very sound reason to avoid plug in tuning boxes - this process does not occur.
Give it a few more days before questioning the clutch, again, if the revs aren't rising without an increase in car speed then the clutch is fine.
When my car was first remapped it behaved similarly. Strange hollows in the response curve and curious mad overboost silliness when hitting 3300rpm. A few hundred miles later and it all smoothed out.
And the clutch survived to 117,000 miles.
Dont' panic yet
