In general, there's not enough of a noticeable difference between the 87 and 89 programs to warrant the expense of an additional tune. We usually end up going with 87 performance, 87 towing, and 93 performance for most applications. If you don't have a need for the towing program, save the $30.00 and just go with the 87 and 93 performance.

Bring back  Windows™ XP and 7. 
Windows™ Vista and Windows™ 8 is a pain in my a$$! 
Windows™ 10 is only slightly less annoying! 
Windows™ 11 is garbage! 
Much to my surprise, I'm actually quite enjoying Linux!
