"Nice chip,improves mid-range performance. It does improve the shifting ratio for a "harder" shift between 3rd and 4th. This chip is $100 cheaper at AutoAnything than anywhere else I can find for the same (posted as Stage 1) programming. Easy to install, well worth the money for an inexpensive mod. I run it with K&N and exhaust and enjoy the results." —Mark A from Indianapolis, IN bought a Jet Performance Module for a 1999 Ford Explorer.
