Early days but I readjusted the zero on my air mass flow and bingo no more hesitation at idle and stall at acceleration. I will know more tomorrow after a good cold start and the drive to work. UK evo thanks for you pointer to zero the amf. Duty cycle is 60-70%(lean) and she is running great. Thanks again for all the support from the forum. I will update over the weekend fingers crossed everyone.
