Sounds good Paul. Thanks for this awsome tune.

It is a huge difference. More beastly and torquey and responsive.
The high IDCs were interesting. Better to richen the hight rpms though.
Again thanks Paul. The tune makes all the difference.

You are welcome man. Let me know if you decide to go to 60's I"ll fix it up for ya.

ok here's the first run..

didnt like 18 deg of timing lol... also in need of some 60's
run two.. only a little kr .8 or so, but IDC is up over 120% so yeah... 60's


btw don't go by what the aem wb says... his wasn't hooked up that was just one of my PID's and for some reason always says 12.8 when nothing is connected.

How often should the ZEX plugs be changed?

same as any plug, just check em every once in a while and when they are fouled... change em. I never go by manufacturers claims of life expectency, I usually check my plugs once a month, and once a week when I"m doing a lot of tuning on my car.
also if you don't have a wideband, once a week should be a good rule of thumb, just make sure to use antiseize everytime.

I've been rocking the Zex plugs for awhile now as well. They are much better than the NGK's were!

Good to hear. Hey they worked nice during our little tuning session.

The NGKs were great plugs they were just a year old but still looked decent.
I'm curious to see how long these Zex plugs last so I can compare.

Oh yeah dude change those plugs. Get the Zex plugs.

Here is a link to the Zex plugs. Ebay is the cheapest. This is the same seller I bought mine from.
