Hey Guys,
A buddy of mine wants to uprgrade to the DSP 5 and wants me to build him a tune for fuel economy, where should I look to improve economy at? If anyone had a good tune that they would be willing to PM to me for fuel economy and possibly a tow tune so I can see what kinda changes have been made and get an idea what to tweak that would be great. Any tips are appreciated! His OS# is 15189044
