SAWS Tuning Torque Limited - 150 Bhp & 260 Lb/ft 


Despite being torque limited to prevent the clutch from slipping our custom remap still produces more torque at 3.3k onwards compared to a "high torque" remap done by a well known competitor. This results in a smooth pull all the way to the limiter vs a car that falls flat on its arse

MG ZT CDTi Auto 

MG ZT CDTi 135 Auto spec 


-Completely standard car with 135 ECU - 125hp & 240lb/ft


-Custom SAWS Tuning remap - 143hp & 316lb/ft


Despite having a healthy MAF sensor this made under stock figures , no doubt due to a life of gentle driving causing a soot buildup. 


As part of the custom mapping process we found the high pressure pump struggled to regulate pressure under high rpm and could cut out if pushed too hard. As such we had to work around this to provide satisfactory results whilst keeping to the customers low smoke requirements and of course ensuring the car doesn't cut out under use.
