The 2020 through 2025 model years represent a golden era for gas truck performance. Not because the manufacturers suddenly got generous with horsepower, but because the underlying architecture of these trucks is more tune-friendly, more mechanically capable, and better supported by the aftermarket than anything that came before them. If you own one of these trucks and you have not explored what it can actually do with a few well-chosen upgrades, you are leaving a significant amount of performance on the table.
This is not a list of expensive builds that require a full weekend in the garage and a second mortgage. These are the modifications that deliver the most noticeable improvement per dollar spent on modern gas trucks, ranked by return on investment.
Performance Tune: Still the Best First Move
On every gas truck platform in the 2020 to 2025 range, a performance calibration is the highest-return modification you can make. The reason is the same across all of them. Factory ECU maps leave horsepower, torque, and throttle responsiveness locked behind conservative parameters designed to cover the widest possible range of drivers, fuel qualities, and use cases.
The Ford 3.5 EcoBoost Gen 3, GM 5.3 and 6.2 V8s, Ram 5.7 HEMI, and Tundra 3.5 twin-turbo V6 all respond meaningfully to a tune. On turbocharged platforms like the EcoBoost and the Tundra 3.5, gains of 50 to 80 wheel horsepower with a tune alone are achievable on stock hardware. On naturally aspirated platforms like the 5.3 and HEMI, the gains are smaller in raw numbers but the improvement in throttle feel, rev response, and torque delivery throughout the RPM range is immediately noticeable.
Tune cost: $400 to $700 depending on platform and tuner. Performance gain: significant across the board. This is the starting point, full stop.
Cold Air Intake: Maximize What the Tune Started
A performance cold air intake is the logical second step after a tune because it feeds the engine exactly what the new calibration was designed to use more of. A properly engineered intake from a quality manufacturer like aFe, K&N, or Volant routes air away from engine heat and into the throttle body or turbo inlet with less restriction than the factory airbox allows.
On turbocharged gas truck engines, intake temperature matters. Cooler, denser air going into the compressor wheel makes more boost more efficiently. The fuel efficiency and power gains from a tune-plus-intake combination are consistently better than either modification alone, and the combined cost is often in the $700 to $1,100 range total depending on parts selection.
Cat-Back Exhaust: The One That Changes the Experience
This is the upgrade that changes how you feel about driving your truck every single day, not just when you floor it. A cat-back exhaust system on a modern gas truck removes the restrictive factory muffler and piping, improves exhaust scavenging, and produces a sound that actually matches what the engine is doing under the hood.
On the GM 6.2, a quality cat-back from Corsa, Borla, or Flowmaster transforms the engine note from muted to genuinely impressive. On the 5.0 Coyote, a cat-back brings out the naturally aspirated character of the engine in a way that no other single modification matches. Power gains from exhaust alone on gas trucks are modest, typically 10 to 20 horsepower at the wheels, but the driving experience improvement is disproportionate to that number.
Cost range: $600 to $1,400 depending on brand and configuration. Stainless mid-grade options sit in the $700 to $900 range and are the sweet spot for most owners.
Throttle Body Spacers and Intake Manifold Upgrades
On naturally aspirated V8 platforms, throttle body upgrades and intake manifold options from the GM Performance catalog and Ford Racing parts division represent strong value. The GM 5.3 in particular benefits from porting or replacing the factory throttle body to match the increased airflow capacity an aftermarket intake and tune combination creates.
These are secondary upgrades best added after a tune and intake, but for owners who want to push further on their gas truck without getting into forced induction territory, they are a legitimate next step.
Who Should Be Doing This Right Now
If you are driving a 2020 to 2025 gas truck and you have not tuned it yet, you are already paying for a truck that is faster than you are driving. These platforms are engineered for more than the factory programming allows and the technology to unlock that performance is mature, well-supported, and priced accessibly enough that there is no reason to wait. The mods on this list have a combined cost of under $2,000 for the full stack, and they will change your perception of your truck completely.
