Your voltage will drop but nothing to warry about. Get an update from Westers PCM to raise your idle RPM to about 600 and you should be set.

Your rpm guage migh be a little off. Unless it's different for the 99's. All the other truck I have logged are in the 525-550 rpm range. BTW, any gtech times with your 99 yet?
