PACKED WITH POTENTIAL
The Power Programmer is designed so that once the parameters are established and loaded, the unit is pulled and the program remains in the onboard computer until you elect to remove it. The HyperPAC is different; this unit stays in place. In addition to the three stages of performance tuning—the HyperPAC has all of the performance programming benefits of the Power Programmer—it also has diagnostics; an engine monitor with a complete gauge display; a dynamometer, which includes such items such as a horsepower graph; and our favorite, a dragstrip program. This program actually monitors real-time engine operating conditions, has a Christmas tree start, displays a timeslip and will provide you with “magazine-type road test” acceleration times in 10-mile increments. It will record and display important engine operating conditions throughout the run and will display drive wheel horsepower versus vehicle speed after each run—in both table and graph formats.

SLICK SLEEPER
Mustangs are usually not candidates for sleepers, because everyone knows Mustangs have plenty of power from the factory for their lightweight bodies. This example, owned by Mike Skiles, looks like an original ’69 Mustang, but as soon as the engine is fired, that logic is thrown out the window.

’88 Blown GMC
In Hawaiian, “wiki wiki” can mean “hurry” or “fast,” depending on its use and interpretation.
New Zealand-born transplant Kim Greenwell’s Kahului, Maui-based black-on-black, 1988 GMC Sierra 1500 is definitely “wiki wiki” with its 500-plus-horsepower, Whipple-supercharged 383 small-block stroker. Greenwell’s basic intent was to build a stock-bodied hot rod pickup that he could use to advertise his automotive repair business, Kiwi Car Care. “I was looking for a nice, straight, rust-free truck that I could paint black,” says the Kahului automotive repair shop owner. “This truck was perfect. It was low mileage, and the price was right. But the brown color definitely had to go!” That’s not the only thing that got changed. “I kept the outside of the truck as stock as possible, but under the hood it’s a true sleeper.”

2025 GNRS Pinstriping Charity Auction
Hot Lines for a Great Cause
Watching the Masters at Work
If you’ve never watched a pro pinstriper in action, your missing out. These guys and gals made it look effortless, pulling razor-sharp lines with an uncanny mix of precision and creativity. Throughout the show, artists set up shop and turned out everything from traditional hot-rod panels to guitars, helmets, and even the occasional skateboard, all in the name of charity. Watching them work was like stepping back into the golden age of custom culture, where a few well-placed brush strokes could transform a basic ride into a rolling work of art.
The Cause Behind the Colors
Every pinstriped piece that hit the auction block wasn’t just a killer piece of hot-rod history—it was also a way to support an amazing cause. This year’s auction raised funds for the Gavin R. Stevens Foundation, a nonprofit dedicated to funding research and raising awareness for blindness, particularly Leber’s Congenital Amaurosis (LCA). The foundation’s mission is to support advancements in treatment and ultimately find a cure, bringing hope to those affected by the condition. To learn more or donate, visit the Gavin R. Stevens Foundation website.
A Gathering of World-Class Talent for Charity
Some of the very best pinstripers from around the world came together to showcase their skills as they created automotive art that was auctioned off each day. This gathering of talented artists was more than a showcase—100% of the proceeds from their work benefited the charity of the year. Every year, a new charity is chosen to benefit from the auctions. For a minimal donation to the charity, attendees brought their cell phones, laptops, or other items to get pinstriped, helping to make a difference.
Thanks to the generosity, talent, and time of the amazing pinstripers, Marshall, Karen, and their entire team, the event raised an incredible $75,000 for the Gavin R. Stevens Foundation!
“We are so grateful to everyone who made this possible! Thanks to our incredible volunteers, board members, and generous donors, 100% of the proceeds will go toward funding research for the NMNAT1 gene mutation causing early-onset blindness. This work is our family’s life mission, and because of extraordinary people like you, we can make a lasting impact for generations to come. Thank you for helping us move forward, one event at a time!”
“A special thank you to the Grand National Roadster Show, John Buck, and the entire team for this amazing opportunity, and for all the great work they do to give back year after year through their events. Our hearts are full!”

Wrapping It Up

Stevens Foundation and reminded everyone why pinstriping is such a vital part of custom culture.
