99 Cummins 24 Valve Tune questions

Recommended Posts

I have a smarty touch on a 99 Cummins 4x4 Reg Cab w/ auto Trans.

 

What settings would you recommend:

 

I have twin set up. S400 AND 63/68-14 turbos. 150 ddp injectors and fass 150.

 

I live in Hawaii....so lots of hills and traffic on the freeway.

 

Looking for setting recommendations!

 

Thanks!

Built trans obviously?

 

I hate to recommend tunes as what is good for me may not be what you want.

 

It is simple to change tunes and experiment. Which tunes have you tried on your 99?

I have tried SW3/5/7....as they have timing. Not much else. Didn't know where to start. I have good top end.....just cruising up large hills on the freeway out here so I'm trying to clean up the initial acceleration.

 

 

Tranny is not built yet.....working on that. Its a new auto. Not getting into the throttle hard until that happens. Just looking for smooth, clean driving.

You've got it figured out. Driving habits will make the stocker last longer. SW 9 would not be able to be enjoyed with a stock trans though. Use the "greatest" timing for the most efficiency.

 

Thank you!
