I have just installed this with an LC-1 hopeing to keep an eye on adverse conditions when using nitrous and my preditor 93 tune. Trouble is, I dont really know what is normal. so far I'm reading 14.5-15 at idle and normal driving. If I rev up to about 3k or lay in a little foot down the road, it quickly shoots up to almost 17. This is without even using nitrous. I thought ideal was to remain around 14.7 at all times?
