By looking at my sig. How many think I should go with a 3k GSK, how many say stay stock RPM's and maybe the effects of going to 3K Negative and positive. Would I gain alot more WOT fueling? Thanks for any responses.

 

With those 60lb springs I'd do a 4k GSK. If thats not your style definetly do the 3k GSK. No down side as far as I can tell. 'Cep my jaw hurts from smiling

 

i vote for the 4k

 

4k helps out alot when towing.

Plus is sounds wicked hearing a Cummins rev that high.

 

I agree on the 4k but I voted for the 3k just so you don't keep them stock

 

I did the washer mod (shimming gov springs)
And my god it was a night and day difference.

Don't keep 'em stock!

 

Do atleast 3k maybe 4k you got the springs for it, your truck will feel soooo much better after you do them, I think it's one of the biggest improvement you can do to a moded truck.

I have read that revving the injector pump that high really accellarates wear within the pump itself. I prefer the realiabilty of the 3K GSK.
