As i already said, a scanner is a good thing to have to check for Kr, maybe more emphasis on the good. I have one so i guess i under emphasize the importance.
I agree 100% with what you are saying. But do you realistically, think that people asking "can i run a 3.4 with my mods and no Kr" and "is the u-bend before or after the cat" are going to spend $400+ [$600 for a HP] on a tuner just to see results after they learn how to use it flawlessly? [No offense to said posters, ya gotta learn sometime]. Learning a tuner, correctly, takes more time then people care to spend, the appeal of instant gratification is too great.
People want cheep easy mods for their car. Parts less then $100 that they have to remove/replace a few bolts to put on. You can tell people on here till you are blue in the face to buy a tuner and learn how to use it but they rarely will. Dropping pulleys sounds too appealing to reason with for some. Best you can do is list sporting mods to combat the inevitable Kr that will come with a 3.4. As i said in my first post , no way hes running 3.4 with his mods and no kr.
