sometimes when i start my car, i have to give it gas to get it started. I then have to hold it at idle for a few secs till it warms up a bit, then it idles fine. I get the same gas milage, maybe a lil better than with my stock obd2, primaries open at 4400 and 6200. I could def feel a difference when i first installed it. Best offer
