Hi People,
What's the safest power increase on a 184bhp 320d without changing internals and turbo.
I've looked around and seen maps that will give you an extra 40 but what else can be done.

Safest? BMWs Performance kit for the engine. I believe it's an air filter, intercooler and a new ECU.

I've got a racechip CR02 fitted to my 320D 184 bhp. Racechip claim 232bhp, had it fitted for 14 months now & no issues to report, just bags of power & torque
