Testing Method / User Experience Highlights

Conducted repeated 77-mile (round-trip) road tests using the same refueling process (timed settle after pump shutoff; often the same station).
Early tests: cruise control at 70 mph; later tests used 63 mph and higher tire pressure for additional savings.
Measured:
- Fuel economy
- Fuel flow (gph)
- Engine load
- Timing advance
- 0–60 acceleration
Checked multiple devices for ECU/indicator behavior (e.g., OBD power light / flicker expectations).
During tuner testing, a Dragy 0–60 device malfunctioned once, so an additional run was performed (acceleration still improved overall later).
After “tablet” tests, checked combustion via spark plug/carbon inspection and internal camera checks.

Key Results by Product (Pros / Cons / What Worked)

1) OBD2 “cats” (~$31)

Result: Did not meaningfully improve fuel economy; baseline stayed around mid/high teens mpg.
Cons: No convincing mpg/HP gains beyond normal variation.

2) Nitro OBD2 (made in China; claims +35% power / +25% torque)

Result: Almost same performance and fuel usage as the OBD2 cats.
0–60 / power claim check: Acceleration was worse than before (about 8.5s vs 8.32s), suggesting claimed gains weren’t realized.
Fuel: Slightly worse than the cats; ended around ~16.45 mpg.

3) 2G Fuel Saver fins kit (~$20; made in China)

Result: Thumbs down—fuel economy was worse than the prior OBD devices.
Behavior: Fins seemed to function more like a windbreak than a fuel saver.
Acceleration: 0–60 was disappointing (~8.76s).

4) Baseline without gadgets

Result: Still consistently bad fuel economy for that configuration.
Best “before major mods” figure: just over 17 mpg (high point of the day before exhaust/intake/tuner).

5) MBRP high-flow exhaust (~$448)

Exhaust airflow check: New exhaust measured around 101 CFM vs old 74 CFM (stock was restrictive).
Pros: Exhaust sounded better; airflow improvement was validated.
Fuel economy effect: Helped—instant/overall mpg improved notably after install (engine load reduced).
0–60: Improved to a new best at one point (~8.13s).

Conclusion: Exhaust was a real contributor to gains (unlike earlier OBD/fins devices).

6) Cold air intake (after exhaust)

Result: Improved efficiency further; instant mpg climbed to >20 vs prior ~15–19.
Pros: Reduced engine load and fuel flow.

7) Super Chips performance tuner (~$461; “mileage save” tune)

Pros: Most consistent “tuned” gains once paired with exhaust + intake.
Fuel economy:
- Hits included about 21.9 mpg, then later 18.78 mpg for the 77-mile test (final reported outcome depends on context).
- With additional conditions (tire pressure + slower speed), the combo reached ~20.39 mpg and was part of the “best overall” claim set.
Acceleration: When measured, fastest 0–60 recorded ~8.01s (tuner + CAI + exhaust).

Overall verified combination result (big claim in video)

Host’s conclusion:
- Average improvement vs earlier baseline (first four round trips before CAI/exhaust/tuner): ~22.39% fuel efficiency improvement
- At 70 mph, improvement was about ~12.73% with cold air intake + high-flow exhaust + tuner

So the “22% better MPG” appears tied to the performance hardware + tuner, not the cheap OBD/fins/tablet gadgets.

Tablet/Air-device type “scam” checks

8) Fer brand tablets (~$35 for 10; claims combustion efficiency/oil life/deposit removal)

Result: Thumbs down.
Generator test: Similar runtime vs straight gas (generator out of fuel around 22m 16s vs 22m 48s with plain gas = ~30 seconds less, not meaningful).
Engine inspection: Spark plug looked basically the same carbon-wise; deposits didn’t notably drop (spark plug turned orange but without clear improvement).

9) Turbonator (~$16; dual propeller boosts mileage/HP)

Result: Thumbs down.
Generator test: Same outcome as Fer tablets—no real improvement.
Operational issue: Needed air-duster help; claim that it “doesn’t terminate the generator” wasn’t supported / it wasn’t functioning as expected.

Eco/Neo OBD-style devices on a second vehicle (2020 Chevy Suburban)

10) Eco OBD2 (~$10; plug-and-drive; 2-year warranty)

Setup: Requires driving for ~150 miles to “recognize driving habits.”
Fuel outcome: After setup and testing, calculated about 22.38 mpg over a 77-mile round trip.
Acceleration: 0–60 around ~7.39s (note: traction control may have held performance back).

11) Neo Socket / Fuel Shark (~$20; claims up to ~20% savings)

Pros: Slightly improved uphill performance (~+1 mpg per checkpoint behavior).
Fuel economy: 77-mile result about 23.36 mpg (very close to Eco OBD2 overall).
Acceleration: 0–60 around ~7 seconds (again, traction control may have affected results).

Baseline (no devices) on Suburban

Result: Host “couldn’t tell” big differences vs devices; fuel economy was very close across cases.

12) Tire pressure + slower speed strategy (not a product, but tested “treatment”)

At ~50 PSI and 63 mph:
- Reported fuel efficiency up to about 28.5 mpg (computer)
- About 26.23 mpg based on fuel added / distance
0–60: Worse due to traction control/traction limitations; acceleration slowed slightly (~7.52s).

Unique Points Mentioned (All Distinct Claims/Observations)

Gas prices causing about $800/month spend; skeptical of MPG claims up to 20%.
OBD2 “cats” passed inspection and had power/ECU indicator behavior to monitor.
Baseline vehicle mileage around 319k on the first platform; multiple repeated fuel pump refuels.
Nitro claimed +35% power / +25% torque, but acceleration worsened.
2G fins kit claimed savings via rear fin placement; behaved like windbreak; worse mpg and slower 0–60.
Exhaust airflow test: 101 CFM new vs 74 CFM stock, supporting the engineering premise.
Cold air intake reduced engine load and improved instant MPG significantly.
Super Chips tuner offers “mileage save”; claims +15 hp / +40 lb-ft (not directly proven), but measurable mpg and best acceleration when combined.
Dragy malfunction during tuner test run; repeat performed.
Fer tablets generator test showed minimal runtime difference and no meaningful carbon reduction.
Fer tables “made in USA” (as stated); Turbonator made in China.
Eco OBD2 required ~150 miles adaptation; claimed up to 15% savings; 2-year warranty noted.
Fuel Shark packaging claim up to ~30% (host paraphrase) / ~20% savings plus extras (cleaner emissions, more horsepower, longer battery life), but real results were close to baseline.
Traction control repeatedly mentioned as limiting 0–60 performance on Suburban tests.
Tire pressure near max and reducing speed to 63 mph produced the largest Suburban mpg improvement.

Pros/Cons Summary (Per Category)

Cheap OBD/fins/tablets (likely “scam” outcomes)

Pros: None demonstrated convincingly for fuel or performance; best cases stayed near baseline.
Cons:
- Nitro/2G fins didn’t deliver claimed HP/mileage.
- Fer tablets showed no meaningful engine carbon reduction and minimal runtime benefit.
- Turbonator didn’t improve generator performance and appeared unreliable.
- Eco/Neo OBD devices on the Suburban showed small/unclear differences.

Real performance hardware + tuning (helped most)

Pros: Exhaust + cold air intake + Super Chips tuner delivered the major MPG improvement.
Cons: Costly; improvements appeared tied to the full setup rather than “plug-in magic.”

Speaker Views (if multiple speakers)

Single main host performing the tests; no distinct additional speaker viewpoints were clearly separated.

Concise Verdict / Recommendation

Skip OBD “cats,” Nitro, 2G fins, Fer tablets, and Turbonator for meaningful mpg/HP gains—this review found thumbs-down results for most (or improvements too small to trust).
Consider high-flow exhaust + cold air intake + a proper mileage-tuning device (Super Chips) for real mpg gains; host reports about ~22.39% improvement on average with that combo.
For the easiest mpg win on the Suburban, the review found slowing modestly and raising tire pressure (within safe limits) delivered the best mpg improvements in later tests.
