Depends on your Service Writer. I have a good friend who wrenches on my Harleys who is a Service Writer at Machens Ford in Columbia MO. When I told him I put a Banks tune on it he indicated I just voided my warranty.
Interestingly - Banks doesn't re-write the codes - just modifies em. (according to Banks) You can also back the tune out and re-install the stock tune. (Don't know why ya would - other than takin it in for a
re-flash update)
I'm thinking - just thinking mind you - if you find a good Writer and Tech, you can get away with the tune and the Ram Air. <---IMHO
Surf those forums too - TONS of great information on there from folks with MUCH more experience than I. I just read alot and try to get the most out of what I got myself in to. LOL!
Sounds like you got the "Drivin" part down good enough. Ya learn pretty quick to keep yer foot out of it.
That Banks Ottomind will lower those RPMS a little more too and you'll get a nice power boost to boot.
The up side to these Super Duties is you're bigger than anything else in the dang parking lot, they ride like 12 year old Scotch....smoooooth and they'll pull about anything you put behind it!
I'm happy to help on the Diesel thing too - I don't know everything, not even close, but I been studyin up!
