This Silverado came in with a persistent engine tick and transmission shudder. After a thorough inspection, we tore into the top end of the engine and eliminated the factory AFM system using our BTR DOD/AFM Delete Kit, complete with upgraded camshaft and lifter setup.

While the engine was out, it made sense to address another common weak point. The factory 8L90E torque converter was removed and replaced with an upgraded billet unit from Circle D for improved reliability and performance.

With everything reassembled, calibrated, and tuned, this truck is back on the road running stronger, smoother, and more reliable than ever.

If you own a newer Chevy or GMC truck or SUV and are considering an AFM/DOD delete, get in touch. We offer a variety of packages tailored to your vehicle, driving style, and performance goals.

This Challenger came in with some issues to fix and for some upgrades as well. The supercharger was a decent upgrade but the camshaft that was installed just wasn’t a great fit. So we pulled the motor and installed a BTR Stage 3 Hemi Camshaft, new lifters and valve springs. We put a performance built NAG1 auto transmission and Circle D converter, added Stainless Works long tube headers and a DSS Aluminum Driveshaft. We went to DeastchWerks for a drop in high flow pump module and injectors. Now all tuned up we’re making 571whp and 558wtq. This Mopar now sits there and chops away as well as will spin the tires for days. It’s now back to the owner and getting some miles put on.
