alright guys I picked up a new truck a few weeks ago

1997 s-10 4.3 5 speed. regular cab long bed

I'm wanting to upgrade the PCM so I can tune it. I'm guessing I'll needing to swap in a 411 PCM?

looking for some guidance from the guys with 4.3 experience

I'll post some pictures later of the beast

 

Cool ! Congrats on the new ride .

Yeah I have heard you need the 411 . S10 guys hoard em like gold haha .
