If you are too lazy to do the research you don't warrant the response for me to "show you"...
This is the only 4 page thread I've seen that has ONE person going on and on about MD spacer not providing gains... there are hundreds of pages from hundreds of users that do show gains.
Doesn’t take a rocket scientist to figure out this thread is pointless. And yes, I felt compelled to state my opinion (and facts) in a pointless thread.

When I ran with my spacer, the DA conditions were about 1,200'. I ran 14.32@97.6mph in sea level air and a 14.37@99.8mph in 1,200' air with a taillwind. Using the NHRA correction factor for 1,200' (.9874 for ET, 1.0129 for MPH), the car would have technically run 14.188@101.08mph. Like I said before, the tailwind was accounting for some MPH increase on the far end so wipe away 1 to 1.5mph. The end result is .14 seconds and 1.9mph in favor of the spacer. Yes, conditions change slightly during the day, but I'm only running over the span of a few hours and no major weather events were occuring. Chances are track temps on the day I ran with spacer were probably closer to mid 60s because it was very sunny and the breeze was straight out of the south.
For my car, the spacer works.

Not sure what the underground weather link provides us as they are calculated data bits from a weather center somewhere else and not at the track. The changes in conditions although small, can be different nonetheless and be a factor.
It almost seems the OP has some computer program that he plugs info in and it spits out data that he relies on.
I just think the guy is blowing up that something doesn't work and he's honestly trying to say that 5hp in the mid and 10 peak hp is able to be determined worthless or worthwhile in a series of drag strip passes stretching over MANY different months and days. If he's such a drag race fanatic and stands that he is somewhat a professional (he never said he wasn't), why does he not utilize a dyno?
His answer is that dynos only provide numbers for bragging rights. Clearly, he doesn't understand dynos are a VERY useful and accurate tool for proper tuning and optimum set-up. If the guy would actually utilize a dyno when he added mods, he probably could have a car that was much better in terms of performance. However, he simply bolts stuff on, runs some passes and decides whether or not they work. Could work for some things, but for a 5-10 hp gain? Not buying that he can determine that and claim .10 difference means it doesn't work...
A lot of these bolt ons are designed for real world and performance driving situations. I was at Mid-ohio yesterday at the track event they had there. There was a G35 coupe and although he wasn't going real fast, I bet the spacer in his application is more of a desired thing than drag racing. The road course guy is driving in a vast array of rpms at any given time. In the meat of the power and at the peak of his rev range at times. Something like the spacer mentioned here would benefit him rather well.
Of course, he probably would have his lap times increase with adding a spacer. So, it probably means that due to the fact he is so damn consistant over the course of 2.3 miles of twisting racetrack, the spacer is worthless...

I recognize some ignorant people on here..
Anyways DaveB can I get those exact dates and times for both runs or you don't want anyone to burst your bubble if there is proof that your mod gained you nothing?

I know I am a bit late, but I have been tuning for years and just wanted to add another:
"Your impression of performance gain/loss is WORTHLESS without controlled dyno conditions to measure output. It's the scientific method without the whole pesky test the hypothesis part. You either have a valid test or you have nothing."
