❓ Frequently Asked Questions
Answers to the most common questions about remapping, tuning and our process. Still unsure? Contact us and we’ll help.
Is remapping safe for my car?
Yes — when it’s done within the limits of your hardware and the car is healthy.
We log boost, fuelling and temps, and calibrate safely so drivability and reliability come first.
Will a remap improve fuel economy?
Often, yes. Efficient torque delivery can improve MPG under normal driving.
If you use the extra power often, expect economy to drop — that’s driver-dependent.
Do you offer dyno tuning?
Yes, we offer dyno tuning — and we also carry out extensive road logging to validate results.
Even without the dyno, bigger builds are logged, adjusted and tuned correctly under real-world load.

What power gains will I see?
It depends on your engine and hardware. Use our checker to see estimates and supported models:

Do I need to upgrade my clutch?
For 6-speed PD130/PD150 gearboxes, a healthy stock clutch is typically fine up to ~250 bhp.
On the PD100 5-speed, an upgrade is usually needed once you go beyond Stage 1.
For higher targets (250+), we recommend a 6-paddle clutch mated with the stock Sachs dual mass flywheel for strong bite and street manners.
Do I need to upgrade my turbo or injectors?
That depends on your target. As a quick guide:
- ~200 bhp: PD150 turbo (GT1749VB) can achieve ~200 on PD130; PD150 is already there with a safe map.
- 220–235 bhp: GT1752/GT1756, FMIC, correct MAP sensor (see our guide).
- 235–250 bhp: GT1856, ASZ/ARL 550cc injectors minimum, FMIC, exhaust, 4 bar MAP.
- 250–280+ bhp: GT1856 is the last true bolt-on; beyond that you’re into GTB/GTD turbos, Firad 80%+ nozzles and a 272 camshaft at 280+ bhp.
What MAP sensor do I need (3 bar vs 4 bar)?
As a rule:
- Up to ~220 bhp: 3 bar is fine (PD130/PD150 have 3 bar stock).
- GT1752: can run on 3 bar.
- GT1756 or larger, or any goal above ~220 bhp: 4 bar required.
What should I check before tuning?
Fresh oil & filters, no boost/vacuum leaks, healthy MAF/N75, no clutch slip, no fault codes.
We can run diagnostics and road logs before mapping to catch issues early.
Can you revert my car back to stock later?
Yes — we always back up your original ECU file. If you sell the car or need diagnostics, we can restore the stock map.
How long does a remap take?
Most Stage 1 cars take around 60–90 minutes.
Custom builds that need extra logging or turbo/injector calibration can take longer.
