Anyone near watford area with vag com?

Anyone near watford area with vag com or can help me with my ibiza cupra. I took it today to torque of the devil to have it rolling roaded and the tried three times but had to let off at 4,000rpm as its running DANGEROUSILY LEAN, they advised a new mass air flow. Has anyone experienced the same or can help with suggestions. Please thanks. by the way my cupra is 51reg done 60k and only has panel filter and uprated re-circ if this makes a difference??

I will try it tomorrow. It feels fine driving it though at the moment??
