We love when readers reach out to us about their builds. Take Teal Sarty's late-model Silverado for example. His 247,000-mile, L5P Duramax-powered Bow Tie laid down 819 hp on the Blessed Performance chassis dyno last weekend. But this is no race truck. It’s his daily driver that doubles as a tow-rig—and it’s often hooked to 20,000 pounds worth of fifth-wheel trailer and cargo. And oh by the way, he tows in this same 800+ hp tune. 💪

Here’s a quick rundown of his HP Recipe 👇
▪️S&S 100-percent over injectors
▪️S&S 14mm CP3
▪️FASS 240-gph
▪️Inglewood-built Allison
▪️Calibrated Power 67mm Stealth (VGT)

Despite fighting an exhaust leak, Straightline Automotive's Douglas Bull effectively doubled the horsepower of his fourth-gen on nitrous during his time aboard the Blessed Performance mobile chassis dyno (1,160-rwhp) at NHRDA’s Truckin’ In Tulsa event. Later on, he left the giggle gas back in the pits to compete in the $10,000 Average Joe Blue Collar class. While he didn’t take home the win, he did bring an ideal truck to compete in the new, daily driver-intended, roll-start, no-prep, 2WD style race. 👇

☑️ Stainless Diesel "Boss" 63/67 VGT
☑️ Exergy 30-percent over injectors
☑️ FASS 165-gph supply system
☑️ Revmax 68RFE
☑️ Hamilton tow cam
☑️ Smeding intercooler, valve springs, pushrods
