won't rev past 4800
 

It's like hitting the rev limiter at 4800-5000.
Using an Accel DFI gen 7. on a 402 LS2
Checked both fuel and ignition rev limits, both set at 7000.
Tried different crank sensor. Help?
thanks

T56 or M6? Also are you reving it in park/neutral or while driving?

Getrag G50/52 Five speed transaxle, while driving and on chassis dyno.
thanks

It turned out to be a bad cam sensor, even though it was a new GM unit.
