Will it hurt to run a Steeda CAI without the tune for a day or two? My tuner shipped blank because my 2014 GT was missing the ECU sticker and it might be a day or two before I can coordinate with Steeda for the correct ECU tune.
Got off the phone with Steeda. In case anyone else is in this predicament, the answer is a definitive NO, YOU CANNOT RUN THIS CAI WITHOUT A TUNE. Stock ECU can't cope with the amount of air now flowing into the intake. You can damage the car by driving with this CAI without a tune. DO NOT do as I did and jump the gun and install the CAI BEFORE you are ready to install the tune.
The folks @ Steeda are good people; I should have known better. After all the CAI is throwing a parameter way out of the range the stock ECU software expects or can obviously handle. A no brainer to have expected and foreseen this.
I'm just thankful I didn't try to drive the thing and merely started it up, backed down the driveway and pulled back in to the garage! Completely my fault.
