No noise just feels like you drive into a brick wall or 2
and its not the same as hitting a rev limit either just a total loss of power at 6K in any gear
tested fuel pressure ,compresion only on cold the back yard way spark etc
As for the program setup its on the base map from Microtec with no changes this setup works fine in another 13BT swopped the computers around
solderd all the connections
As for fueling she is a tad rich on idle(12.?) "sounds like a mild bridge port" and then seems to go to +- 13.7 from 3k-4k and then from 5k to wall 12.? again
exhaust was a tad small would not boost more than .3bar now i can push 1.3 after the change from 48 to 63 induction is 58 from cone filter to turbo inlet

I had the same problem and it turned out to be a clogged cat. Try disconnecting you cat and running the car around the block. If the powers back, thats it.
