Was wondering what you guys thought about that sonnax wire on your truck? Got a 2008 Dodge 1500 Big Horn and was curious on if it was worth it to put that on my truck or should i just leave it alone and not worry about it? The truck has got 20,000 miles on it so it is still under warranty. I just dont know what to do, but i dont want to have to worry about my tranny blowin up on me like my last truck did. VERY EXPENSIVE TO FIX!!!

 

The Sonnax does boost line pressure and increase firmness but I would reccomend buying a Superchips tuner so you can have control over your shifts, TM, MDS..etc Best tuner for 06-08!

 

I got a Superchips, just havent hooked it up yet. So what you are saying is that using that superchips, you dont think i really need that sonnax wire. And if so what % would be good for TM
