That is a small enough difference that it could be chalked up to a dyno inconsistency.
Yep.
The source I got the graph from did 5-10 runs stock and 5-10 with the spacer and picked the best of each. The variance just from stock vs. stock was well about 2 hp.

you know even if you boost its recommended to use the spacer.
i got the copper iso
perhaps it will help, but spending how much on 2 hp? doesnt seem worth it. Like Sopranos said, a CAI and tune on an 05+ mustangs nets near 30HP sometimes.
Those spacers are what, $150-$200?
If I paid the same price per hp for my cai/tune it would have been 3 grand...
IMO its a huge waste of money.
