Ive been tuning my car for partial throttle for the last couple of weeks on my way home from work. So i get it dialed in pretty good high 13-low 15s from 19"-5". All of a sudden the last couple days my car has been reading low 11s and even 10 at idle. I havent changed a thing. Its gotten a little colder out (10 degrees) Any idea what could cause this.


Im tuning with crome.

No ive left all the extra tables alone minus idle speed. Ive only tuned off the tables

 

does the car drive the same? check your plugs....this is a longshot but it happend to me before- check your wideband sensor, maybe it needs recalibration or is old
