Altho, yes, more air is coming in and the comp is probably tweaking, disconnect the batt for abit......reset the ecm.
Then, let it idle for about 10mins when u reconnect the battery.
Do our trucks have the idle relearn process?
I know on my car, when u disconnected the battery, you had to do an idle relearn or it would idle erratically.........you had to put it in drive, and sit there with your foot on the pedal for 5 mins and then turn off for 10secs, and idle again in drive for 5mins.......
don't worry about it...lower idle is fine and higher oil pressure is good...my oil pressure is all over the place most of the time I am only concerned when I have it floored and it is reading low!!! as for idle don't worry about it...with my AEM and all the mods I have I idled at 500rpm when I put in the Granatelli it went to 600rpm
i remember reading about that idle relearn. I think we do have it. but its not automatic every time u disconnect the batt. u gotta do something to trigger it. search ssf...i think i read it there. A whole tps iac adjustment tutorial
