1999 Serria 4.8L


Recommended Posts

Can anyone tell me about a 1999 GMC Serria 4.8L Vortec, auto trannie

 

1. What size the injectors are ?

2. what is the stock HP and torque it was rated ?

3. What does the funny shape of airbridge from MAF to TB do ?

4. Why the injector flow table in the PCM has the same value for all MAP loads which is not normal to other model years ?

 

Thanks,
