That's the talk going around the fourms. A small few see merit in the concept saying when your cruising down the hwy your only using 1/4 throttle other see it as a seat of the pants feel for the quick throttle response on low end opening the throttle less to archive the same speed. All I can tell you is I watch it being done they did a relearn on the computer customer went out and drove it came back real happy! What does that mean I don't really know but I was give one for test and will post what I fine going to do some dyno runs mpg test before and after if it look good on a personal level. I also think that a change like this will need tuning work also to get the best results.

In one of my forums this site was pointed out to me to view the groove tech That are drawing comparisons! Just read through the data, The dyno testing is interesting.

Here is what I have to start my testing. Obd1-2 scanner and the digital timing light!

It looks like this grooving tech is spreading!

I'm skeptical but I have an open mind. Please keep on with your experiment. I am hoping that you are on to something. Good luck.

Testing will start tomorrow! With the state smog testing this will be the before numbers first!

As I start collecting data one thing one has to rememeber is the condition of the car or truck your working on. The testing equipment in that test. I'm using two scanners a Auto X-Ray EZLink and a newer Actron CP9185 both do obd1-2. The newer scanner when hook up and scanning runs the Idle up an extra 100-200 rpm's I down load new updated software which helped so now it only idling 100rpm higher. All the data looks the same from both scanners at the same rpm's so I will keep using it to print my data out.
First up we did a idle test with the two scanners recording a run cycle about 20seconds long at normal operating temp of 195. A driving test 45 mph and a freeway test at 65 mph. With this data we know the truck is running normal show no codes. On to smog testing next!

Remember the only thing that was done was a oil change. cap rotor and plugs are three years old.

When one is test a product the issues of Credibility come to mind and how one proceeds is important! So with out spending a lot of money one can find way to address the issue!

As I have been doing this testing I'm finding other company are doing something a long the same lines in throttle body spacers. Which is a little different but more examples that the process of grooving is said to work. Watch the video!

You should do a bit of research on fluid dynamics, then maybe let this thread die...

Would you please post some of your results
