Power by stage
Stock is Skoda's figure. Stage 1 to 3 are the tuners' own claims, in PS or hp as each states them. APR's figures come from its Golf GTI Mk8 test with the same engine, at the engine, on 95 and 98 octane; most others don't say which fuel. The top of Stage 2 needs the particulate filter removed, which isn't road-legal; about 367 PS is the top with it kept.

Software only
299–350 PSOn 2020–2024 cars, the Continental Simos 19 engine computer is flashed through the diagnostic port; APR's list names the Octavia RS with engine DNPA (its coverage list). A remap claims about 300–350 PS with the filter kept. For the 2024 facelift, RacingLine lists the "Octavia vRS IV.5 2.0 TSI 265ps" for its plug-in box only, and APR, REVO and TVS list nothing yet.
Typical cost: remaps $526.95 (APR), £658.80–£720 fitted (REVO, RacingLine at QT Performance), €499 (TVS) or €650 (BR-Performance); RacingLine with gearbox tune £960 fitted; plug-in boxes €199–€459 (RaceChip), €689 (DTE) or £849.55 fitted (RacingLine PCM).List prices, Sept 2026, before shipping, import tax and fitting.

The DSG: check whether it's locked
RacingLine is blunt: "If you own a 2022+ Octavia vRS… your transmission cannot be tuned" until the gearbox computer is unlocked (its Octavia page). Its dealers can unlock it by cable, or replace the circuit board with an unlocked one (3–4 hours, gearbox tune included). RacingLine's gearbox tune raises clutch pressure from 12 to 19 bar, "up to 650Nm". APR's DQ381 software ($649.95) says "most vehicles with a build date of 01/2022+ are not currently compatible". BR-Performance charges €400 for its gearbox tune.
Intercooler, intake and downpipe
324–389 PSWith the filter kept, Stage 2 means an intercooler and intake with a matching file: RacingLine's Stage 1+ claims 367 PS / 539 Nm on 98 octane and APR's Stage 2 353–358 hp. RacingLine's full Stage 2 (389 PS) needs a high-flow cat downpipe and is "not applicable" to cars with the filter, and exhaust makers list the petrol RS with a filter from 2020.
Typical cost: intercooler £839.99 (RacingLine) or $1,177.98 (do88); R600 intake bundle £773.35–£812.22 fitted; HJS ECE downpipe with filter £2,695.20; filter-back exhaust £793.91–£1,530.89.List prices, Sept 2026, before shipping, import tax and fitting.

Parts list
- Intercooler required
RacingLine intercoolerdo88 intercoolerWagner Competition intercoolerMTM intercooler
RacingLine says the stock one suffers "serious power losses during hard driving" (its page); its replacement is £839.99. do88's lists the Octavia RS Mk4 at $1,177.98, and Wagner's comes with a German parts certificate.
- Intake recommended
RacingLine R600 intake bundle
RacingLine's R600 intake and turbo inlet bundle is £773.35–£812.22 fitted at QT Performance, and RacingLine says it adds "10+PS".
- Downpipe only for the higher files
HJS ECE downpipe with filterMilltek downpipe with HJS catMilltek race-cat downpipeScorpion sports-cat downpipe
HJS's pipe keeps a catalyst and filter and is ECE-approved for the Octavia NX with engine DNPA (£2,695.20 at Milltek, its UK distributor). Milltek's pipes bypass the filter (£1,070.78 with the HJS cat, £752.80 with a race cat), and Scorpion's is "for motorsport use only".
- Filter-back exhaust optional

These are for sound: Milltek's ECE-approved system is £1,530.89 (its louder one £1,209.19) and Scorpion's £793.91.
Bigger turbo
410–458 PSTwo routes are listed. APR has a file for the bigger Continental turbo from the Golf R and S3 (part 06Q145703G), claiming 410–419 hp in its GTI test. RacingLine uses Garrett's PowerMax GT2260S, a direct fit on the 245 PS engine, and claims 439 PS / 529 Nm on 98 octane with the filter kept.
Typical cost: Garrett PowerMax turbo £1,495 on sale; RacingLine's Stage 3 package £4,659 (AwesomeGTI); TVS Stage 3 software €999.List prices, Sept 2026, before shipping, import tax and fitting.

Parts list
- Bigger turbo required
Garrett PowerMax GT2260SRacingLine Stage 3 packageGolf R / S3 factory turbo
Each turbo needs its matching file, plus the Stage 2 intake and intercooler. The gearbox needs its own tune, and on 2022-on cars that means an unlock first.
Built engine
no pump-fuel figureBAR-TEK lists a built-engine bundle for the Octavia RS (NX, engine DNPA): forged pistons with steel rods, a cylinder head kit, a Golf R upgrade turbo, a fuel pump, a 4" downpipe and an intercooler, for 600 hp / 650 Nm at €15,513.53 before fitting (its guide). But that figure assumes 102-octane fuel, which Israeli pumps don't sell, and the bundle lists a clutch for the DQ250 gearbox rather than the Octavia's DQ381. TVS offers Stage 4 software for €1,499 with a forged engine, without figures. So we don't give a Stage 4 number.

- What is my car's build date, and is its gearbox computer locked? If so, will you unlock it, or run a lower-torque file?
- Which file will you load, 95 or 98 octane, and what does the tuner publish for that exact file?
- Is my car a 2024-on 265 PS facelift? If so, what can you offer beyond a plug-in box, and will I get a full reflash later?
- Does the downpipe keep the particulate filter and carry ECE approval, so the car passes the annual test?
- Are you an authorised dealer for this software, and can you get the parts in Israel?
- Will you log and dyno the car before and after, say whether the figures are at the engine or the wheels, and can it go back to stock?
