question on tuning lmm

[02bigstrokin]

my boss has a 08 lmm and we put efi on it. question is how much can we go and still keep the dpf?

will really depend on the tuneing but about 75-80 rwhp hp over stock is about the max even that can clog the dpf. or cause more regens.

ok thanks, we put a 20% tune on it and he likes it but we were thinking about doing 25%. i think thats flywheel hp. you think it would be alright? he needs to get rid of the dang thing all together.

Maybe try loggin soot mass with different tunes. Whichever creates more would be the one to stay away from.
