Throttle Body Calibration
Is there such thing as the fly-by-wire calibration? I just put some insulation in the car and I am a tad afraid that the pedal does not move quite as far as it used to. Is there a way to check that all the way down is open 100%?

Find someone that has HP Tuners or EFI Live. You may be able to get a bluetooth/wi fi OBD-II reader and use a cell phone app and read the TPS sensor for about 30-50 bucks. It would take a pretty large amount of insulation to knock your pedal off of 100%, your throttle body should be wide open with your pedal about 1/4 - 1/2 inch from max. The last little bit doesn't do anything, it isn't like old cable driven throttle bodies.

Any code reader that is able to read live sensor data will display throttle angle.You can also pop off the air ducting and see if throtle blade goes 90 deg open at full throttle (key on Eng off)
While it open, clean the throttle blade and MAF!

I didn't even think about the free scanners you can use at the parts store. Good call.
