the wrench light did not come one until 30 min after the reflash truck still runs the same as b4 the reflash, and the first thing i suspected was maybe the eot and ect were not within limits but i have a coolant filter and a 7 month old oil cooler i hope i dont need another oil cooler

That could be possible especially since you haven't replaced your diablo with custom tunes yet(atleast going by your siggy). I did a bypass and I already had tunes that had the EGR turned off even before I did all my modifications, so I never had an experience with the wrench light with regard to EGR flow.

wrench light comes one while normal driving and no hard start, and i have a full egr delete maybe its detecting low egr flow....i hope thats what it is

I don't get the light on short drives (less than 10 miles) ... but if I get on the highway for any amount of time it will come on.

Got my stored "wrench light" code read at the Ford Dealer today ... as I suspected, it was the DTC P012F for the oil cooler efficiency.
So I say to the Tech ... "but you guys just changed my EGR & Oil Coolers less than a thousand miles ago". Tech says that in his experience, its probably a dirty oil temperture sending unit (3C3Z-10884-AA or Motorcraft SW-6052) ... he suggests cleaning it or replacing it. He said "its definitely not a plugged oil cooler".

Light still comes on when I'm on a 30 mile or so steady highway drive.
I'll follow up with findings.

Actually just picked up a new Temp Sending Unit today; should get it installed in the next few days. I'm also gonna get an Edge Insight monitor to get a visual on the Temp spread.
