I purchased a 2012 sel hatch from a toyota dealershship that has a non ffv engine. My first tank resulted in a mere 28 mpg and the engine gave off a strange low tone after the automatic tranny shifted. I opened the hood for the first time on thursday. The car had a k&n drop. I took the filter out and noticed that a large hole had been cut out of the air box and an open four inch hose was under the box. It looked like someone had attempted or had done the newmission mod mentioned in this forum. But I did not see where the hose would get air on the inlet side because there were no holes or slots cut in the grill. Where does the hose go to get air.?
I stuck the hose into the air box and the car does seem to run smoother. If I fix/complete the newmision mod, what is the comparison to stock? Mpg increase? Hp increase? Water or dirt issues?
I need to decide quickly if I need to take car back to dealer so I don't have time to read through all the forums and comments. Any quick replies will be greatly appreciated.
Btw, she is FAST!
Look forward to hearing from the FFs.
