i believe na-banggit na po sa thread din na to ung mga nakita nina bluegsr and raijuta na values.

vacuum reading would almost be the same after installation (2 inHg). before installation, depending on the condition of your auto. 17 inHg on the average, 20 kung very good condition pa.

Vacuum gauge is tapped at either PCV or brake servo.

Anything else sir?

Okay... as ghosthunter has said, testimonial evidence doesn't really count... and mr. rajuta's actions have not exactly been encouraging... bordering on scandalous.

With great respect, sir, the vacuum issue is not what we would like to see addressed... as so many have mentioned previously, it both the overall effect on the automobile and the possibility of poor NOx emissions (which were mentioned in this thread from almost the very beginning) that are of contention.

Violations of NOx emissions automatically make a car fail EURO4 testing, and as most manufacturers have complied with such, it may not be long before our government implements them.

The lean-burn engine is nothing new, but by making the engine work outside its electronically controlled parameters, one cannot assume the lifespan, cleanliness and performance of the engine will not be affected.

Many modern engines are already running a fine line between compromised performance, fuel economy and pollution control. Changing an airfilter or muffler won't affect these greatly, as these only control the amount of air entering and exiting the system. But ALTERING the intermediate steps in the process can mess things up very badly.

So far as I can see, these threads are going nowhere. It is only the hardcore skeptics who are staying in, and who are facing an ever-changing array of salesmen, 'testers' and inventors. I doubt anyone who has stayed this long is really willing to be convinced of anything... and unless some solid information and reliable data comes up, no one will be.
