Real Dyno Results
Real results. Every chart and table on this page comes from before-and-after pulls on a professional DynoJet 224X. No simulations and no marketing guesses. Where a number is calculated instead of measured, we say so.
How we tested
Stage 1 complete-system results used a performance chip, cold air intake, and cat-back exhaust on the same vehicle, measured on a DynoJet 224X under controlled conditions. Chip-only Stage 3 numbers below are proportional estimates from those complete-system pulls, not separate chip-only dyno days.
Stage 1 complete system results
Combined Stage 1 chip + cold air intake + cat-back exhaust.

Visual dyno evidence
Test case 1: Stage 1 / Stage 2 comparison
Before-and-after pull comparing Stage 1 and Stage 2 upgrades on the DynoJet.
Test case 2: 3.8L naturally aspirated, Stage 2
Stage 2 versus stock on a 3.8L naturally aspirated engine, 92 octane. The Stage 2 horsepower curve peaks near 355 HP. The stock horsepower curve peaks near 325 HP.
Test case 3: 2013 Jeep Wrangler 3.6L on the dyno
2013 Wrangler 3.6L on a Dyno Dynamics dyno, with an aftermarket intake on the 3.6L. The sheet in this photo reads 252.0 HP and 231.2 ft-lb. It is one pull, not a before-and-after Stage 3 comparison.

Stage 3 chip-only estimates
These are estimates, not separate chip-only dyno pulls. They use a proportional share of the Stage 1 complete-system gains above so you can compare chip-only contribution across the same vehicles. Years match the Stage 1 table.
| Year | Vehicle | Base HP | Estimated HP after | Estimated gain |
|---|---|---|---|---|
| 2001 | BMW M3 | 333 | 356 | +23 |
| 1994 | VW Jetta VR6 | 180 | 195 | +15 |
| 2002 | Cadillac Escalade | 255 | 273 | +18 |
| 1996 | Acura Integra | 142 | 160 | +18 |
| 2002 | Ford Mustang V6 | 270 | 286 | +16 |
| 1999 | Chevy Silverado | 255 | 282 | +27 |
| 2002 | Honda Civic | 137 | 151 | +14 |

Stage 4 dyno: Honda Ridgeline
Chart labeled 2026 Honda Ridgeline 3.5L V6, stock versus Stage 4 plus a cold air intake. It shows a peak of 247.5 HP and a max gain of 25.6 HP, with torque peaking at 280 ft-lb.
Common questions
How much horsepower do these Stage 1 kits add?
On the vehicles we dyno’d with a Stage 1 chip, cold air intake, and cat-back exhaust, measured gains ranged from about 28 HP to 81 HP. The Nissan Titan showed the largest complete-system gain on this page.
What was tested on the DynoJet?
Stage 1 complete-system results used a performance chip, cold air intake, and cat-back exhaust on a DynoJet 224X under controlled conditions. The charts above are separate pulls: a 3.8L Stage 2 comparison, a single 2013 Wrangler 3.6L sheet, a WRX STI intake and Stage 3 sheet, and a Ridgeline Stage 4 plus intake chart.
Is Stage 3 chip-only measured or estimated?
Estimated. The Stage 3 table applies a proportional share of the Stage 1 complete-system dyno gains. It is not a separate chip-only dyno day.
