I’m looking for a reputable mapping company in the East Manchester area and only if you have actually used them please, so you can give an honest opinion. Thanks.

I used Quantum for my 4.4, has performed well 2016 Black SDV8 Autobiography
2013 Grey Black Edition SDV6 (lasted a while but gone now)
2005 Grey Supercharged Sport (gone but never forgotten)

Out of interest what do you achieve by remapping the 4.4d V8? MY17 RRS 4.4d V8 Autobiography - Aintree Green (also referred to on Topix as British Racing Green)

A large but safe increase in torque and bhp.

This is from Quantum's site
Original BHP 335
Tuned BHP. 390
BHP Increase (%) 16 %
Original Torque (Nm) 700
Tuned Torque (Nm) 820
Torque Increase (%) 17 % 2016 Black SDV8 Autobiography
2013 Grey Black Edition SDV6 (lasted a while but gone now)
2005 Grey Supercharged Sport (gone but never forgotten)

One question - what is the rated input torque of the gearbox? It's all very well increasing the power of the engine, but the driveline has to also be able to handle it. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

So is there only one member who has mapped his 4.4 on here?? Anybody else?? Thanks.

I've mapped a few SDV8 L322's

Hugely impressive above 2500rpm
