put a Cone filter on the MAF then the MAF to the Supercharger. After starting the car, it ran like crap, surging and such running really rich I could smell gas bad. You think that maybe the MAF being so close to the supercharger is causing turbulance and false readings from MAF? Or do you think that the airflow just changed so much it needs to be tuned?

Seems to me like having the IAT sensor on the non boosted side of the intake would kinda defeat the purpose.. It'll always read low due to volume of ambient air passing by..
Putting it on the boosted side after the aftercooler would make more sense to me..

thats how vortech does it from the factory...

however, there are a couple of threads on the other site that say what your saying,

along with a quote i posted from jerry W

The air temp sensor MUST be moved, this is not an option. There are basically four things that control an engines likelyness to knock; Fuel octane (meaning its ability to resist autoignition), combustion chamber design, cylinder pressure and air temp. When you compress air, the temp goes up. If you don't move the sensor you have no idea how hot the air is going into the engine. If it's a 20F day or a 80F day, the temp of the air going into the engine, and thus it's timing requirements, change. Look at an '03 Cobra, Lightning, Roush StageIII, Saleen, even an old SuperCoupe, where is the air temp sensor? In the intake after the cooler. Why? Because you MUST know the air temp going into the engine to control the engine correctly. Now, some will say that the Cobra and Lightning have a sensor before the blower, they do. They also have one after...Every OEM does it on their blown cars, there is a reason for that and it's a good one.
