So what kind of gains and potential are released by bumping the timing 16* when you do basic mods on these cummins (gsk, fuel plate, intake, exhaust, etc..)

a grand thats nuts my locl diesel shop does mine for free everytime i need it

There is a big seat o pants meter difference in timing, I have ran 15* to 22* and now 30* ... 22 was the funest to drive on the street and 30 just flat out pulls ( above 3k

)

Well 30 degress is completely different than 16 degrees. I dont imagine there is many street trucks running that kind of timing.

I agree, but I still felt a difference when I went from 15* to 20*

Good input guys. That sucks they are tryign to charge so much and a lot of you guys get it done for free or 85$. Must be some bum diesels shops or something

But the person charging 3k for the job IS a cummins dealer

When mine was set at probably about 10-11 degrees exhaust temps were uncontrollable and my fuel mileage was around 13. I bumped it to 19 degrees and fuel mileage went to 19 and my exhaust temps still peg the gauge but come up way slower now.
