I switch my 5.7 vortec from the 99 black box to the 411. I put in a 2002 gvan program and recently switched out the tranny parameters from a 2002 manual camaro in order to match the manual tranny in my jeep. I only got one tranny code after the switch but now the truck won't rev above 2000 rpm. Is it some type of abuse parameter or torque cutoff that's stopping me? I'm posting the latest tune and a log file.

Edit: It would rev above 5k with the original Gvan program.
Edit2: Lextech suggestion of B1207 set to zero fixed it.
