Well, I have my '88 Ranger running again, after setting in my driveway
for 4 months. During that time I was forced to drive my wife's '09
Mazda5 which also has a 2.3L engine.

The Mazda5 makes the Ranger look like a led sled! I need to get more
power out of the the Ranger's tired old engine! Has anyone here tried
a high performance computer chip? Are there any available for my old
truck? Do they really work?

Thanks!
