Stage 2 comprises of
- ECU remap upgrade
- Custom build full race exhaust with 200 cel high performance cats
- High performance air filters give enhanced power and torque.
No other mechanical modifications are required.
Power is increased by 75bhp @ 5500rpm and torque increased by 120nm @ 5000rpm. All of our dyno measurements are recorded at the wheels (you can calculate back to flywheel by allowing for 15-16% power train losses (Mclaren’s stated measured drive train losses).
The addition of the 200 cel race cats and high performance air filters add both both torque to the low end but also far greater higher rpm breathing so the power gains are deepened and extended throughout the rev range, torque is the big gain, 140nm @ 5000rpm feels astonishing, by opening up the breathing from the exhaust you are in effect unlocking power rather than make the engine work harder.
The map has been developed to be relatively calm at lower rpm, under 4,000rpm the car feels relatively standard but from 4000rpm all the way to 8000rpm it would be fair to say the performance is ‘shocking’. A wave of torque lifts the front of the car and squats the back down to such an extent that its hard to describe, it is an utterly transformed drive but retains complete smoothness with no peaks or troughs in the power delivery whatsoever. Its such an improvement that if you dont like it we will take it off and refund you in full.
The work comprises:
- Full vehicle inspection and condition report
- Full custom build exhaust complete with 200 cel race cats in type 304 stainless steel with custom designed tips For full details, images and video of our exhausts in action see HERE
- Removal of cars under trays and rear difuser
- Multiple dyno runs to ensure standard car is performing within parameters with live data logging
- Removal of cars wheel arch liner and removal of ECU
- Mapping of the ECU on a bench using software only (we do NOT open up the ECU)
- Re-installation onto the car and multiple dyno runs with live data logging
- This process is repeated up to 5-6 times to custom tune the map to your car
- Re-install ECU
- Re-fit wheel arch liner
- Re-fit rear difuser and under trays
- Road test with live data logging
- Back on the dyno for further checks if there are any issues
The work takes a minimum of three days (we can provide a courtesy car if required).
All work is covered by our comprehensive 5 year warranty on identical terms to our standard vehicle warranty (terms for this can be found HERE
