RE: TB coolant bypass
To my knowledge the only temperature sensor that the computer reads comes from the MAF sensor. This temperature drop across the element in the MAF sensor is a linear equation that basically equates air flow and density, which gives input to fuel for the proper mixture. The theory being that with colder denser air you dont need as much fuel to get the same amount of HP. That being said, what the mechanic states is exactly the opposite of what really happens. I have thought about doing this mod myself, because in warmer climates of the south there is no need to heat the air before detonation. The reason Chevy has this coolant tube through the throttle body is because they have to design a fuel system that operates in a wide range of operating conditions, from Alaska to Florida and all parts in between. Im no mechanic, but I would think there would be no problem in doing this mod. Please anyone correct me if Im wrong, because as I said, I too am considering doing this mod.
