I would look into the Pulstar claims a little further before you part with your money. n r h s a reputable builder on this sight performed a few dyno runs with these plugs and you might be interested to hear his results. There are also quite a few members here that have tried those plugs and have reported no gains, worse gas milage, and marginal gains which could be attributed to many factors.
One of the things that caught my attention on the Pulstar web site were the dyno runs for their plugs. They had separate sheets for torque and hp. Funny thing was, torque and hp were not the same at 5200 rpm. Very deceptive and if you will lie to me once........

Yeah, I'm very skeptical about any claims of HP and TQ gains with just a plug change. I would like to hear some members experience with the plugs.

I have experience with plugs, but in a 615 hp racing engine, we had some dyno time and did nothing but change the plugs, we indexed them, shaved the gound down a little and opende the gap some, end result was almost 4 hp gain, thats in a 615 hp racing engine turning over 7,000 rpm's, our bikes would not even notice or feel a gain if any even shows up on a dyno.

Post number 260 is where I asked about the fraudulent dyno charts. Post 264 incognito then claims that his plugs will lower rpm,at a given speed without any changes in gearing. All the while he claims to be an experienced mechanic. Still has yet to answer regarding the fraudulent and deceptive dyno sheets.

1st look at the run numbers... 2nd look at the scales HP/RPM... Torque/RPM.
I have been looking at these dyno sheets for awhile now. I have also talked to some local dyno shops & a major Magazine Tech writer/Editor. He told me this happens more often than he would like to admit. Most of the time he catches it... however some times it gets past him (and goes to print). And he gets 100's of e-mails, phone calls & letters asking why torque & HP do not cross at 5,252 RPM? He said the dyno is not always set to the same scale for HP & torque (when this happens HP & torque do not cross at 5,252 RPM).

This bike was ridden to the dyno shop with a brand new set of OEM Spark-Plugs installed it hit the dyno already at operating temp... from the ride there. Several pulls were made... the highs & lows were thrown out. The best averages were kept and graphed on these two sheets (HP & Torque).

The Pulstar Pulse Plugs were installed per instructions... the bike was ridden on the street for the ECU to learn the Pulstar Plugs... it also hit the dyno at operating temp.

These are the results.

That is a difference of 10 between the two. I don't buy it. After personally witnessing the other garbage you have tried to push over in your postings, I would be hard pressed to believe much of anything from you either.

The above link is for a dyno chart where pulstars were compared to regular OEM plugs. Same bike, same conditions, same dyno, only difference is the guy that performed the test, was not trying to sell anyone anything. He ran the tests to find out what would happen. See for yourself what happened before you go buying these plugs.
For what it is worth, I have seen people on this forum that have reported back adverse results. That thread is no longer here though, I wonder why?
