If i got a mail order tune would it matter if i had headers or not? Will nelson have to do anything different with the tune if i had headers. Ill be getting them in the future just not immediately. So will it really matter?

Thanks,
Derek

 

Usually he wont have to change anything, it depends on how lean he has you running on WOT. He usually shoots just rich enough to keep enough fuel there if you got LTs.
