Instead of sarcasm, how about some skepticism. These claims always seem a bit optimistic. From the first post:

A 50 percent increase in gas mileage is very good. Sounds too good to be true, especially since this is in closed loop.
475 AWHP on 550cc injectors is also right at the limit.
As far as the pressure sensor being damaged, I don't know if it is true. There is at least one claim of the factory MAF that stopped working after the honeycombs were removed. The flow will certainly be more turbulent and it would be difficult to predict how that flow will affect the pressure wave created by the vortex generator. Whether it is permanent damage or just erratic performance, there have been people that have had problems. Most have been corrected by replacing the honeycombs. Some have had them for extended periods without problems. Just trying to present both sides to this possible consequences of this mod.
