Question about 1993 GMC Sierra C2500
The 08 diesel vehicles have a particulate filter much like a catalytic converter an a gas engine, these exhaust cannot be modified by removing the filter . The PCM will monitor this function and alert you with a service engine light if an issue is detected . Removing this filter will also cause the vehicle to go into a low power mode until the problem is repaired . It is also illegal to remove this filter as it part of your emission system for that vehicle . I don't think your programmer and intake would cause you any issues.
