Jump in Log Crankangle Vs Map

[pattmall]

i am running an Peugeot engine XU10J4Rs with lot of preparation on the engine :
-Forged piston compression ration 12.2 : 1
-Forged conrod
-Camshaft catcams 4903156 (280°)
-Head of the engine is prepared for better flow
-4 throttles of GXR 750 SRAD
-Fuel is E85

The engine is running not so bad but as i am trying to optimise the fuel map and the vaccum signal i have done a hispeed log cranck angle vs Map. And in this log i see some jump on the cranck angle is it normal ? or do i have some problem in my configuration?

I think what you are seeing is the -2 on the 60-2 wheel.
