Hi all,
Looking at remapping my M140i and have been exploring a few options. I have heard a lot of positive news about Litchfield’s tune. Any views on best place to go for OEM feel at reasonable cost, with decent power gains and some level of warranty protection?
Thanks

You don’t say where you’re based? Performance Torque have done a few cars for me (Midlands based) & seem to have plenty of BMWs visit them - they will dyno as well rather than some firms claiming gains but not supporting them with before/after evidence on a dyno/rolling road.

You might be worth posting the same question on one of the BMW forums as well.

I asked Charlie from Surrey rolling road (who must have dyno’d more than anybody in the country?) and he said Litchfield are the standout map.

I had DMS map my old m135i and I must say that was a stunner, so it will be between the 2 when I eventually get round to mapping my new m140i.
