Callaway shows their tuning program for the Chevrolet Silverado & GMC Sierra

Callaway is renowned for building high-performance Corvettes, but the company has recently announced its plans to offer a new tuning program for the 2014 Chevrolet Silverado and GMC Sierra.

The packages are currently under the process of being developed, but the company plans to offer a supercharger package for models equipped with V8 engines.

Final specifications remain unconfirmed, but Callaway expects that the supercharged 5.3-liter V8 should be able to generate more than 450 hp (335 kW) which is an increase of 95 hp (70 kW). Similarly, the supercharged 6.2-liter V8 should generate more than 540 hp (402 kW) which is a gain of 120 hp (89 kW).

The company is also in the process of developing an entire range of accessories including tire, suspension and wheel upgrades and if that was not enough we can even expect a body kit as well as interior styling components.
