I went to amsoil also. What do you use for the 6speed and diff. Also what air and fuel filters are the best?

 

Roger, for the diffs it depends on if you tow or not. If you do not tow or tow a little 75w90 is your best bet if you tow alot or tow heavy 90w140 is what you need, and you might need to toss in about 8oz of friction modifier if you notice alot of noise from the axels. for the tranny it takes a 5w30 sincromesh oil. I'm still a bit confused about the exact oil since the NV5600 is VERY tempermental about the oil you use, and not only that but the availability of parts for the NV5600 are VERY few and far between. if you have the g56 it takes atf+4 and so far isnt as tempermental as the NV5600.

as far as air filters, well. . .youve seen what Ive done fuel filters, these are the only filters I would use since fleetguard is a division of Cummins, Fleetguard FS19579 10 micron or the NEW Fleetguard FS19800E 7 micron

the 10 micron is $12 and the 7 micron is $15 at geno's

 

SouthernHotrod,

How many miles will it take for the Edge Juice/Attitude combo to pay for it's self in increased mpg? I have seen the cost on these types of programs and always wondered what the ROI time is. BTW, if I were to need more HP then what this CTD has I would have bought a Freight shaker with a 600 HP cat under the hood.

 

charles, I know guys that are pushing 750hp from these trucks and one guy that dyno'd at nearly 1200hp with all sorts of drugs

btw, you would have to do alot of driveing to make the money back on that egde, or for that matter, any module you put on. Personaly, I doubt you would ever see returns.
