Hi All I'm new to this forum and am really enjoying the info! However I'm a little confused concerning Hypertech chips...I called and confirmed that they do not support shifting options for 08 Expys yet one or two people have claimed the effect on the shifting was worth the cost...can someone clear this up for me...and Thanks
Some of the programmers allow changing the shift points and trans line pressure by 25, 50,75,100%. Unfortunately, that was not an option for the 08. What can be done is raise/lower "redline" before shifts +/- 100-500. The rest of the drivability feel comes from the program. I ran mine on the 87 tune and +400 on the rpms. Sadly, I sold my Expy, but still have the programmer if interested.
