As for the "leaning out", what makes you think this do you have a guage(AFR) ?
May be wise to change the fuel filter in that case, the AFR at all speeds loads is controlled by chip with trim inputs, a dodgy CTS can do this but would effect it at all times not just at top end.
If you know your car is defo leaning out it can only be lack of fuelling which could be something as simple as a new filter needed or pump/regulator on way out.

Thanks for you comments,
It deffo is leaning at top end evidence is melted spark plugs. Had Steve Scott hang a pectel on it all sensors ok, flow tested the grp a pump thats ok too.
Im under the impression that it is a problem with the chip, the fuel pump never used to prime as long as it does now.
I was thinking that if the chip controlled the fuel pump then that could point to the problem also.??
Also last time I drove it at high speed it held back, a few seconds later it cut out. I pulled to the hard shoulder switched off waited awhile then restarted fine drove home...
