This is our most popular tune for M42/M44 engines and has been something that we have consistently been improving over time. We offer 3 different variants of this tune. Full stage 3 includes BDS cams, ported throttle body, cold air intake and ECU tune on the dyno.

Option 1 retains the standard air box and a 7000rpm limiter. Option 2 includes a cold air intake giving 3-5hp over the standard air box with a 7200rpm limiter and is +£100 plus VAT. Option 3 is the same as option 2 but with different cam timing suitable for track use and features a 7500rpm limiter. For a road car we recommend options 1 and 2 for better low down torque.

The picture shows a before and after for the tune.
