Message: [QUOTE="2012dually, post: 1285263, member: 23182"] That is some very helpful Information!!!! So step by step tuning procedure for the 6.7: 1) Remove/increase all limiters 2) Increase fuel unitl constant smoke/haze under load, then 3) Increase air/boost where needed 4) Add timing So what is actually causing the 6.7 to throw rods? is it too much commanded fuel and boost down low or too much timing? From what I have read if you add fuel down low and retards timing it will help spool up as the fuel is injected later therefor more energy is in the exhaust vs used to force the piston down. How to add fuel: In the SCT Software I do not have "injection Quantity" only Injection Quantity to Energizing Time Conversion which looks to be the same thing. Also I cannot seem to find the Torque to fuel conversion in SCT like the MCC does. It seems like MCC has renamed most of ther maps and tables etc which makes it more user friendly. So add fuel in the higher rpms (say above 1600) to avoid too much torque down low and save the rods? [/QUOTE]
