I am building a 5.7L Hemi from a 2007 Ram for a project. I am changing the stock cam and springs. I am going to use a comp computer controlled roller cam (.528/.531 lift and 216/220 duration @.050) I am pretty sure I will need a custom tune for this to work. Any suggestions as to who and where I can send the ECM and have it custom tuned? Any help will be greatly appreciated!!! Thanks for the help...........
You would just get a diablo or sct hand held tuner and get either custom tunes via email from someone like hemifever or get it dyno tuned at a shop that does cmr tunes for diablo, no need to send your ECM anywhere
I'd get a programmer, like the DiabloSport Predator or InTune, get in touch with Johann at DSP and fill him in on the engine specs. He can put together a base tune, email it to you, you load it on the tuner then plug the programmer into the truck and load it.
Run the truck and log what parameters Johann asks for, then email him those logs and he will modify the tune.
Easy enough. Just call them when you are ready and have a tuner in hand.
