Smokey, I am new to this and was wondering what the advantage of the 270 sweep has?

You want to be able to read the gauges at a glance. When the gauges are nearing the redline, you are too busy driving to be staring at gauges. So you want the area around the redline to be spread out and very easy to read and interpret. For tranny temp, the red line is 225º, so you want the area between about 200º and 230º to be very visible and easy to tell the difference between 220º and 225º. For boost, the red line with a stock turbo is 25 PSI, so you want the area between about 20 and 25 PSI to be big enough easily tell the difference between 22 and 24 PSI.

Many gauges have only a 90º or 180º sweep, crowding the the numbers together so it's hard to tell the difference in a small change. 270º spreads out the numbers so you can crowd the red line without exceeding the red line - and at a glance - when you are towing and busy dodging traffic and outrunning the Dodge to the top of the pass.

The ISSPRO pre-turbo color-coded pyrometer is not only 270º, the color coding makes it even easier to read the gauge at a glance so you can maintain between 1,200º and 1,250º EGT while climbing the mountain, dealing with traffic, and keeping an eye on that Dodge.
