Are there any Cat mechanics on board here that have access to the tune specs for Cat engines? I need the injection tune specs for the Cat 3116 MUI injected,GM medium duty truck, 300hp @ 2600 rpm,732 tq.@1560 rpm. Cat shows that was an available tune for medium duty trucks. Specifically,I need the timing dimension and the fuel setting dimension. Also ,it would be nice to see if my current 215 hp engine has the correct pistons for that tune. The perf spec for my engine is 2T5437,serial number 9GK04633 .Thanks in advance if anyone has the info or knows someone that can get it for me.
We're already discussing it. He seems a bit knowledgeable of the little kitty to say the least. Think I'll listen to him.
So far it seems like a piston change unless my engine has the 2 piece pistons already. He's checking on that. A cam and turbo change as well and a Cat 300 hp/750 tq certified reliable tune is doable. A bump from 215hp/605tq to 300/750 would make me happy enough I think.
