Got a 99 Tahoe that I will be doing a conversion to diesel. Would love some insight to any obscure details that I might have missed in doing research for this project.

Original: 5.7 vortex injected 2 door Tahoe with 4l60e.

Conversion: 6.2 TD studded heads with mechanical IP. ESS will be from 6.5 front mounted sensor. TPS is from humvee style TPS with a 5v reference. Hydromatic Power brake and steering. Low stall TC for 4L60e.

Concerns.
- OEM computer to control the 4L60e with lower stall converter.
- O2 sensors (check engine light)
- 4L60E ability to handle the torques without towing
- ABS issues
- speedo
- existing fuel pump over pressuring the IP.

Thanks in advance for any insights .
