well thats what i assumed as well seeing as it hasn't been that overly hot...but i got a call today when i left work the radiator was right but fittings were wrong so jim was machining em down to fit said "it happens all the time, never had any problems with custom parts...im not leaving till this thing is done, its been here to long"...the stock trans never did me any wrong handled the best it could with everything i threw at it, to some point i wanted to find the "breaking point" so say that i completely killed an allison.

i still believe efi is way better for dmaxs then hp tuners and talked to numerous people on dieselplace.com and they have never had problems with efi...now that my trans is built i'll see what it puts down with PPE and then ill stack the edge on that and see what it does, know people that have done it and was alright.
