this pulley setup retains stock belt?

[03mgmcobra]

http://www.billetflow.com/supercharger_pulleys.htm
With 4 Pulley snub Idler Kit (3-100mm and 1-92mm)

Pulley Size....Belt Size........Gates Part No......Gatorback Part No.
2.76..............75.1".................K080751...............4080750 (with 100mm Idler) (Stock Belt)

This means I can reuse the stock belt? This is the setup I think I want and keeping same belt is a bonus. Less hassle. Does this sound right? Sorry, pullies rookie.
Also, do you guys install these at home then drive to your tuner?
Do you need to buy a SCT/Predator to do the tune? Or does tuner have software/interface?
I tuned my '96 w/ a SCT X2, my tuner guy was kinda smoke and mirrors and i didn't ask. :bored:

You can use the stock belt w/this set-up or a 74.5 belt.You will for sure need a tune w/this upper.I used VMP tuning out of Orlando and am very satisfied.Amazon is a vendor on this forum who also comes highly recommended.If do do a mail away tune be prepared to datalog the car!

yes that is correct. you can retain the stock belt with a 2.76 or 2.80 pulley and the 4-piece billetflow idlers (3-100mm, 1-92mm)without any further modifications.

i did and it's working well
