Do we have any vendors here that can service my needs? There are some guys on Duramax Forum but some of them are ******. Since I have been on here longer and know alot more people her I was interested if anyone on here could do a EFI Live tune with a 5 position DSP switch

 

from what I understand, its not a 'good' idea to have the dmax on multi-position switch for the reason that the Allison takes a little while to adjust to the driving style for which its tuned for?

 

im fixing to move my friends tune to dsp5. Not sure on what all needs to be done yet. havent looked at it a bit.

 

I think it is some wiring and then you are done. About the not being a good idea to have the multi position switch and it being a problem with the tranny, there are too many out there that run the switches on the LB7 and LLY with no problems, I have never heard that. I will do some research but I really want different tunes because of towing, economy, and performance. I didn't know if Black Bear or Nelson messed with them much
