Sorry for the confusion,
The sizes are available in:
2.7
2.8
2.9
3.0
3.1
3.25
The SS Silverado tunes that come with the Radix are fairly conservative, so a 3.25 and a 3.1" are usually ok to install without a tune. However, a tune will compliment it. I've installed a few 3.0" pulleys with no tuning and the truck produced ZERO KR, but I think it's pushing it with no tuning. That was on good 93oct here in San Antonio.
The pulleys are $99 and they are in stock and ready to ship. A tenth lower from your current size is going to give you about 10hp. .40 tenths may not give you 40hp though .
thanks, :burnout:

what have you seen with an LQ4 that runs a stock 3.1" pulley?
