Thanks for all the info folks
Had a mate plug it in today and 2 faults found both relating to tb
The butterfly isn't closing properly on idle and at first he couldn't get it to accept the reset ? After 4 attempts it reset the idle and all was good however just noticed it's crept back up not much though !
Spoke to rtech today and chap I spoke to seems confident it can be cured so fingers crossed I haven't killed me throttle body , and all being well Friday remapp will be done
Thanks again folks
