Kerry,
First, the "IQ" that Smokin is referring to is the new electronics controller that Cookshack is now using on their new FEC smokers. It has a much more definable temperature process and has less than a plus or minus four degree swing in the temps once it reaches the temp. If you really need a more closely grouped set of temps that you will be cooking at, you might want to look at upgrading your smoker with a new IQ4 controller.
Second, "preramp" should really have been typed pre-ramp. In the many versions of FEC 100 smokers, the original ones, and all the way up to about three years ago, had an augur that deposited pellets directly in the firepot. It was a straight feed as such.
During the process of getting the UL certification, the whole pellet delivery system was moved up about 5-7" with the augur dropping the fed pellets onto a downward sloping ramp into the firepot. This design change was to avert any burnback of fire through the augur into the pellet hopper.
Third, the 1, 2, 3, that Tom is referring to is a very small dial on the circuit board of the pre-IQ4 smokers that would change the feed process of the pellets. Factory specifications were to be set on 2 but in actuality sometimes came out at 1. At 1, the feed process would occur quicker during the "timed" temps of Smoke and 180 on the old Traeger controllers. This is turn led to higher temps than needed.
Fourth, from your description, you must have a pre-IQ4 FEC which means you have a smoker with a Traeger controller in it. The Traeger controllers, by their own design and nature, will have temp swings above and below the temp you set the controller at. I don't have a problem with this. As with any other smoker, you need to learn how to cook with what you have. I have both a pre-IQ4 FEC and an IQ4 FEC. Each one cooks in its own style. I learned that through my own experience and help here from the forum. There is nothing wrong with it. We have used both smokers at competitions and have done very well with both.
Remember that when you have the temp swings, think about the average overall.
I have to go rest my fingers now.
