Re: Sparky's 1978 Silverado Build "Addiction"

I apologize, I've been posting a lot on Instagram and slacking here. So, here's an update:

Pictures:
1-2. Current view of truck. No, it's not a 4x4 now
3. I purchased the Dirty Dingo lower Lower AC mount and compressor. I didn't like how the upper located compressor took away from the look I wanted.

I finally got the engine started. I runs pretty good at idle. However, it does run rough and somewhat sputter when you apply acceleration.

I'm getting the following codes:

P0650 Malfunction Indicator Lamp
P0068 Throttle Body Airflow Performance

The engine was tuned with Speed Density tune in the original truck configuration. I'm guessing that when I rearranged things and relocated the MAP I need a re-tune?????? I'm gonna have to ask the professionals!!! Sounds great otherwise. Maybe Mongocanfly will chime in with a solution?

Thanks Mike
