Mr. Dale Davis,
-Are you trying to put up a challenge here about EXACTLY how the IS300 Engine works along with the schematics and how it integrates with the MAF (mass air flow, that is the correct terminology) meter?
-We have done extensive research and development in our design of the Air intake system and subcomputer that works flawlessly with the OBDII computers in the IS300.
-Our dyno sheets was done independently and if you want to put up the challenge we will reveal the company (very reputable company) and have testimonies from the employees and owner as to the results of the dyno runs.
-Why in the world would you even try to run the car without the MAF meter, IMO that is like playing with something you have no idea about, I am surprised you did not destroy the engine.
-The other thing that really make me sad to see and really troubles me is the misinformation and confusion you are trying to create here. Your statement of the IS300 using OBDIII tells me you have no idea of what you are talking about. All vehicles manufactured TODAY including all Lexus Vehicles are OBDII compliant and not OBDIII. OBDIII is still under development and it differs greately from OBDII. Here is a link to enlighten everyone on what is OBDII and the proposed OBDIII (read the whole article, you might learn a thing or two):

-Also SRT is very big and concerned with emmissions and that is why we also make sure that emmissions are within the 50 states regulatory requirements.
Here is a word of advice please do not try to say anything about something you know nothing about! Sorry to sound so arrogant, but it really annoys me when people make assumptions without knowing anything about what they are making assumptions of.

I don't know if you all know that the IS motor is a "positive pressure motor" and has been designed with the factory airbox (made by GM) as a necessary part of the equation. It needs pressure to run at it's optimum efficiency. The AFM is an imbedded design (within the intake pipe from the airbox)unlike the previous Toyota AFMs. There were tests run w/o the AFM (was a complete dog, of course, but had to satisfy a question) and one with an open filter system. Both were terrible! The ECU taking feeds from the sensor ECU was getting crazy trying to set/control the fuel/air mix throughout the powerband. The 3 computers in the IS are OBDIII, and there's not a whole lot you can do to trick them.
Sorry to rain on the parade. Just be wary of anybody pushing these open filter elements as performance enhancers. They're "dehancers" for the time being. Don't worry, we're working on this with TOM'S.
Happy motoring!
