Just thumbin' thru aq magazine and happened to notice that you do raise the rev on the duramice to 4400rpm's. Just curios as to why us guys with cummins(granddaddy of them all) cant get a few more r's? If this has been answered already than I appollogize, I did a search and didn't really find anything. Thanks Bud.

 

programmers set it up to about 3700

 

Come on guys! There has gotten to be an answer for this. Quad????

 

Can't be done without a programmer. Quad's product fr the D-max is a programmer. The boxes just fool the factory computer into more power. No way to fool the RPM's to the computer without messing with everything else lie trans shift points, pressure, ect. It would be a train wreck!
