Just had the e4od in my 96 Powerstroke rebuilt and wanted to know what the actual operating temperature was so installed the gauge. I also added a much larger transmission cooler and a deep pan on the transmission. At first I thought the gauge wasn’t functioning at all, but after a few trips around town, I noticed the pointer on the gauge was actually climbing. Normal temperature readings are around 140 degrees just driving, which is great from my standpoint, knowing that excessive heat is what destroys an automatic transmission! Riff Raff Diesel is one of the ONLY companies that I do business with and they have NEVER let me down in the past eight years since owning Ford Powerstrokes! Thanks Clay and the whole gang at Riff Raff, I appreciate your integrity, which is very hard to find these days. I’m a customer for life!

Looks great. .

Replaced my ev-1 gage with this gage because of the programmable warning light. Because of the way the ev-2 gauges work it's a much cleaner. you no longer need a seperate amplifier box. Riff Raff's shipping was fast as always

It's my 1st isspro gauge, its bright, its easy to install, and really readable. Also compared to my (what I thought was awesome) autometer gauges, I can't wait to replace the other 3 now. Even the needle lights up!!
