Well from what I have heard the reason they wont let you watch the test is due to osha regulations and it is a hazard. This is from the CEO not the workers like nathan. Thats why they won't do anything on my car (well that and another reason I wont go into publicly). I told them I didn't want them dicking around with my fuel lines to install a flow gauge and I wanted to be inside while they tested my car. I agree with sean the fact that they won't let some r&d be done with outside vendors makes it seem sketchy. Especially since the gains they are claiming are in the variance range of the dyno. I think that any hp gains they can provide are easily dialed out by any car with a turbo. Mostly because in most turbo cars the ecu has so much control over the motor it can dial out any variances. N/A cars seems to have a bit less control which is where the plugs seem to shine but like I said all of the numbers I have only seen from 1 day (3 consecutive pulls) on the dyno. There is no data of the same car being dynoed at a later date which I think is where the answer lies. Hell if we could find some free dyno time I have a fresh set of pulstars sitting on my desk. Then we could test them in a few different scenarios and get some better data on them.
