Slower acceleration after cleaning MAF and changing the air filters

gaveup

Uhm, not for anything, but this has to be the absolute worst possible way to measure any sort of acceleration. When you're dealing with just mere seconds, there are far too many factors that would go into the recording alone that would mess these numbers up. This is one of those times where even a garbage gtec would be a better way to guess acceleration times...

Like, how are you measuring the start and finish of each run? Are you basing it off a speedo or what? Most speedometers are not accurate 100% of the time the higher up you go. Unless you have a 1/4 mile perfectly measured out and have a sure fire 100% method of measuring the time, you're numbers will always vary.
