was the ripp a huge improvement have you had any problems with it, how about axles or drive shafts. i have allready replaced ds front axle. the ujoint clip popped off and reamed out the hole dealer said under a load it happens due to bad design they had allready replaced several under warranty i guess driving thru 3 feet of snow is to much i was surprised i figured they would say 37's voided warranty they said only true fix is to get aftermarket axles thanks mopar for the cheap parts
First problem, I was running the Hypertech program, and had to remove it. ( I believe the Ripp box expects stock parameters, so the performance ones messed this up)
Then I had to install an update, it was easy and made everything much smoother. Lots of extra power, especially around 3k rpm.
Last is the water/ methanol injection. That chit is hard to find in Florida where we really never see a winter. Its recommended to use -35 or -50 window washer fluid... Took me three weeks to find a store that had two in stock. The parts guy thinks they get it occasionally by accident. lol
Now I am going through the "break in" period that the ecu needs to "learn" so about two weeks and I could tell you much better.
fwiw, I run 37's and 5.13 gears, and am adding the mbrp cat back as soon as it gets here. Stock d30 and rear d44, running a JE Reel up front and custom (local) DS in the rear. (Keep those joints greased)
Even with ANY aftermarket performance mod.... give yourself about 800-1000 miles before passing judgement. The ECU really does need this amount of driving before it settles in and everything works to max. (I know its been an arguable point, but it has been proven in the real world)
