Mercedes ML W166 2013 AdBlue Delete, Customer had “No Start After X amount Miles”, So we tried to perform a full reset of the system and it failed. This is not ideal when the vehicle is in daily use, So the customer opted that we delete it and now the issue will never arise again.

Ford Transit 2.2TDCI 125BHP - Vehicle come to us in limp mode due to DPF issues, We've tuned off the EGR and DPF so these components will no longer be an issue.

Mid-tuning, customer also opted for our stage 1 tuning package

ORIGINAL - 125BHP_330NM

JNS Tuned - 180BHP_420NM

Customer reporting this van being very sluggish even before the limp mode error, after tuning, this vehicle now has it's power unleashed, theoretically tuning it into a higher spec Ford Transit.
