[QUOTE="Bill Ellis, post: 613005, member: 59929"] An answer to Bob_S2's question. I'm guessing the factory tune is one that balances performance and economy; not optimized for either. When performance is optimized, economy suffers. When economy is optimized, performance is reduced to some degree. I'm an easy driver and rarely, if ever, drive in a performance mode. So, in order to get better economy, I don't care if wide-open performance is somewhat less than it is now. Others want better WOT response and don't care if it hurts economy. An optimized tune can do either, but i doubt do both at the same time. If I'm off the trac on this I'm sure Wayne will chime in and correct me. [/QUOTE]
