How it drives
Proven on the road.
We don’t just measure peak figures on the dyno. We road test every vehicle and analyse the data from the drive – every road, every throttle position, every load – so it drives right across the whole rev range.

Citroen C4 2.0 HDi 163 BHP
Custom calibrated by Martin at Pendle HQ – torque, fuel, boost and timing as one, so the power comes in smoothly across the whole rev range.
Power and torque
Standard to Pendle tuned.
What your calibration covers
Every map. Calibrated as one.
Every map in an ECU works with the others. We calibrate the whole strategy together – so the power comes in smoothly and the engine stays inside its limits.

- Fuelling + rail pressureFuel matched to the air.
- Boost controlDelivered where it’s requested.
- Injection timingClean, efficient power.
How it drives
Pulling out of a junction.
Low rpm, part throttle – where everyday driving really happens. It pulls away cleanly the moment you ask, with no flat spot and no surge.
How it drives
Open road, foot down.
Boost builds exactly as it’s requested and the torque rises in one clean line to its limit – strong, progressive and controlled.
How it drives
Braking, then back on the power.
Off the pedal under braking load, then straight back on: boost and torque recover smoothly, with no hesitation and no step.
How it drives
Smooth, linear torque.
Torque rises evenly with your right foot – no dead band, no step. Kinder to the gearbox, dual mass flywheel, drive shafts and engine mountings.
On the day
On our Maha dyno.
Your C4 runs on our Maha MSR 500 before and after its calibration – a four-wheel-drive dyno with the front and rear rollers electronically synchronised, safe for modern four-wheel-drive systems.
On the day
A sealed, air-controlled cell.
Air at the front simulates driving at up to 140 mph, and the same volume is drawn out at the back – so the pressure in the cell stays balanced, run after run.
On the day
Logged before. Logged after.
Every vehicle we tune is data logged before and after its calibration, and every log is analysed into an in-depth data log report.
We don’t chase the limits – we calibrate to work precisely within them.

Every engine custom calibrated
Calibrated by Martin.
Each and every engine is individually calibrated on our Maha MSR 500, for every throttle position and every rpm. No two engines are identical – we don’t stop until the calibration is right.
“We don’t chase figures. A correct calibration is safe, reliable and smooth, with the power delivered exactly where it should be – that matters more than any number on a printout.”

What our customers say
Do it right the 1st time.
If your going to do it then do it right the 1st time and get a custom map wrote for your vehicle and your vehicle only - as long as Martin is trading then I wouldn’t look elsewhere!!!
What our customers say
More than just a generic flash.
I’ve put 20k on it and it has been and still is a pleasure to drive. I wouldn’t have trusted anyone else… it’s more than just a generic flash.
What our customers say
The ONLY company I trust to remap my vehicles.
I have used Martin since 2008 when he was growing his business & continue to use him, his knowledge & experience are second to none. The ONLY company I trust to remap My vehicles.
What our customers say
Martin knows exactly what he is talking about.
Remapped my Vito sport x 3.0 and I have to say it was impressive for a van...... service was excellent and Martin knows exactly what he is talking about. Can only recommend this company.
