Overview:

Take control of your GM Gen V LT1, L83, or L86 engine with Terminator X!

The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more.

The 3.5" touch screen LCD handheld contains an easy to use calibration wizard as well as tuning and gauge display functions.

The Illustrations are Sweet, Storyline… Great!
Format: Board book
This book is sturdy and has a wonderful message. My grandchildren love it! If you are the one who presents 2 children in a classroom or other setting, most children will really love this book. The durability of the book is great. The illustrations are sweet. The review platform does not allow for me to enter an age span. It does not allow for me to enter multiple ages. It seems to force you to Select one age. I would say that having raised children of my own, I would start reading this book by one years old, but the average child I guess would best benefit with between ages like two and four. The book could be read up to people who are like six years old if they just love a sweet bedtime story.
