Depends on your tune. Your tuner can "lock" the idle setting to a certain range and even if you set it beyond that range on your handheld, it won't do a thing.
i was hoping to be throwing my video of my recently installed cams by today, first my spring compressor didnt come in saturday, so I went to do it without it <with plenty of walkthrough help from darren> and a guy I work with.
through a few minor screw ups I used a phaser bolt and had to remove it, was waiting to get a new one to torque phasers all the way down.
seems the guy that helped didnt hand tighten the passenger phaser down enough and it slipped off the cam and sent the chain whirling around ruining any chance of it being in time.....
already called my uncles to have them tow it to their shop in the morning and re-time it.....god i am SO PISSED
