Ok, so overkill on a couple of my mods, but at least they are in place for future mods to come, and overkill is fun, right. I had a 180° Mishimoto t-stat installed at one point, and check engine light would come on every morning on way to work, 190° cured the issue, besides, does 10° really make a huge difference? Fans are set correctly. I’m looking at a Getrag diff upgrade kit now, comes with heavy duty axles, hubs, and of course 3.73 diff. I notice in pic it has 3 bolt for driveshaft instead of the 4 vehicle has now, do I have to upgrade the driveshaft as well? Also, by doing that, do I have to drop rear sub for the shims that come with 1 piece driveshaft kit? And lastly, does anybody know of a good Dodge tuner that has a shop in Los Angeles/Ventura County area? Thanks for all the help
