Those pulstars I plan to give them a run in the near future. I already put them in my friend's Z06 Vette and he is getting something on the order of 30 more miles per tank based on the range function, but we are waiting for a few more weeks to measure out the mpg properly.

I am using Torquemasters right now, been doing so for about the last 2.5 years. I had tried them previously before I did 95% of my current performance modifications and didn't notice much of any improvement, but after I did a modified intake and exhaust and then put these plugs in, the improvement was definitely noticeable and really helped burn the gas, which at the time was when I was still living in Mexico City (high altitude and bad gas).
