...I don't think it will work that way, scientifically.
theoretically, Lets say the intake is drawing 100 cfm of air (just to keep the numbers round) through the 3.5 inch tube the MAF would see 100 cfm. Once the turbo begans to builds boost it will create more air than the 100 cfm that the TB is drawing. At that point the 3.5 in tube is closed (because if u don't the air will escape your filter) and all incoming air is from the turbo...there is no lag in air, just the constant increase that the turbo would create anyway....
