The J&S system is nice. Looks like your getting a little time being a contortionist under the dash. LOL. Apparently it would work with the knock sensor existing on the N/A's. But it carries a nice price tag with it too. About 650 beans.
Yes it's not cheap, but considering it has the ability to pull timing out if individual cylinders if it senses knock this 650ish could save you 4-20K by saving your motor from blowing.
It actually pretty simple to install, took me 3 days after work to install it due to the old instructions I had and a miscommunication between me and the manufacture. I could do the install now in 2hrs!
BTW the L/HDs have knock sensors installed. There just turned off, this kit uses the factory knock sensors even on the L/HDs.
