Start with what you want the truck to do
A useful upgrade is one that fits the job. Before choosing components, explain how you use the truck and what you want to change about its performance. A daily driver, a towing truck and a custom project are not interchangeable applications.
The shop’s approach is application-specific rather than a standard package for every diesel. Existing modifications, the truck’s platform and the conditions it sees all matter when discussing a direction. Custom tuning and parts installation should be considered as part of the truck’s setup, not just as an isolated purchase.

Look beyond a horsepower number
Power and responsiveness are part of performance, but so are drivability and durability. BPE considers known drivetrain strengths and weaknesses when recommending components, including upgrades when they make sense for the application.
Our project gallery shows a Dodge Ram and a Ford F350 build. Those are individual projects, not a promise that another truck will achieve the same result. Your starting platform, existing setup and intended use need their own discussion before the shop recommends work.

Discuss the whole setup before selecting parts
A performance conversation may also involve drivetrain work or brake and suspension choices. Vehicle weight, towing demands and driving conditions are relevant to those decisions. The right question is not simply which part makes more power, but which approach fits the way the truck will be used.
Bring a clear description of the truck’s current configuration and any unresolved concerns. If the truck needs diagnosis or maintenance, discuss that alongside the proposed upgrade. Call or email the shop to talk through the project; this website does not list fixed upgrade packages, guaranteed gains or approval terms for financing.

Have these details ready
- The truck’s year, make, model, engine and current modifications
- The change you want in power, response or drivability
- Normal workload, towing demands and any current repair concerns
