Hi guys and Girls. I am having issues with a 911 Super Sport Targa with the engine breaking down (judder) at 2500rpm perfect under this and you drive through it at 2600rpm. So issue is limited to around 100 rpm around 2500 rpm.
I have changed DME Relay, Coil, Leads,Cap and Arm.
Apart from the crank sensors which are next Im running out of ideas.
Any one had same issue and fixed it.

The Engine has just been rebuilt but issue was there previously so no air leaks on manifold etc gaskets all new.
