If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

While the chain design is somewhat different, is based on principles similar to the Bosch HY-VO chain product, purported to be quieter and more efficient.  Reliability stats are not yet available.

Hmmm...

I can tell you this, since we had the entire timing set done on the Lincoln, KR is a rarity. I would have thought my sensor was broken if it wasn't happily adding.

For the 1st couple of months after we got it back, never saw more than .09. Yes, that is correct. Two months in I finally got a +3 on an extended logging/hunting session.

Now i have to look and see if i got the updated parts.

"Timing system" is right that's a lot of parts that need replaced

You would be surprised how hard a time I have convincing people of that, LOL.  Unfortunately, there are a LOT of moving parts to this system, and if just one goes wrong, it casts doubt on the rest of them.
