Hiddeous will have a better idea after he views your tune and logs.

Let us know what you find,I am interested in the outcome as well. Ive seen your other post on the HP site but it may take a while to get an answer there.

Yeah, no luck as of yet

Ive attached a pic of datalog tonight, as you see it starts at about 2500 rpm comes right after 3000rpm every time

What your seeing is Torque source 1 (Torque truncation). Have not found a fix for this issue. You can set all the RPM for torque source to 6500rpm and the the issue still stays there. Good luck.

I have tuned with both SCT and HPT but prefer SCT - what ended up being the fix?

Basically setting up torque managment to work with the car rather than blanket disabiling it, which we found in Phils case was brining in ETC torque managment on the shift that he as having issues with.

Once the torque managment was working properly the trans tables need to be set up to perfrom correctly with the increased torque avaliable

So you couldn't actually stop the throttle plate from closing ie Torque souce 1 was still registering? You just tuned around it?
