Do I need to change the LED flasher relay with my Savvy LED taillights?

I think it's really just designed to avoid the rapid flash when you put in LEDs, I don't think it's heavy duty or anything like that. It doesn't change the flash rate when the current draw drops like a stock relay would to tell you a bulb is out.
 
I have the Novita LM470, it is comically erratic. It works 100% but it is always slightly off in timing, like listening to a 6 year old play Beethoven. It is obvious every time I use my signals that the timing between flashes is off. Totally irrelevant but somewhat irritating.
OMFG!!! I nearly blew milk out my nose, reading this... such an accurate description. Anything better out there?

Wiring in resistors and using the stock flasher is not a bad alternative. You'd get reliable stock performance with none of the aftermarket flasher quirks.

Only downside is the PITA factor of splicing wires, which is not too bad.

I like these. I cut off the duotap vampire clip and hard splice into the wiring. You can still remove the resistors via the twist lock connection. Stick them to a metal surface and you're good to go.

I have all LEDs and I'm running the Novitá LM470, but I'm curious if there's something else out there that's just plug and play without dyslexic blinking.

Not really as far as plug and play goes. The LM470 is really the only proper flasher for your year with aftermarket lamps. That's why I alluded to the resistor option, because it is a more reliable option, not plug and play but would have better (stock-like) results.
