Message: [QUOTE="TARM, post: 372641, member: 578"] These are just educated guesses The issues I can see: Is this a engine that has had compression changed head work etc? I would think that would effect things. But in general talking to guys that program tunes, idle as that takes some trial and error to get just right. Then you have a turbo that has seen very limited use as far as I know in the 7.3. Only a couple GTX4202 I know of. I am not sure how much that effects things but I would think the less that combo is around the harder it would be to have a good base tune for it to start with. 400% can only make so small of changes. I think it ends up taking alot more playing with PW ICP etc.. There is not as much wiggle room between just right and way to much or too little. Getting cruising smoothness is something that can take some tweaking as well were you get that off on feel to the throttle as you are getting down to the lower amount of fuel that can be injected and get smooth throttle. Still I think its a good challenge. We know it can be done in the cab by professional as well as private tuners doing just their own trucks. I think it would a very good thing to see what it takes to get one dialed in remotely with just data-logs and input from the owner/driver for the tuner to go off. I like the idea. Hopefully the outcome could help further the quality of the base tunes for those wanting to run larger injectors like 400% on the street. IMO it can only help things. [/QUOTE]
