325i, 3l, 3 stage manifold, remap with nox delete running stratified with a slightly broken nox sensor!
With 325i is no brainer to remap. 330I is marginal BHP improvement maybe 10-15bhp...
To really make it work and sound better with either NOXEM or Remap/NOX code out it would be best to remove the exhaust mid section with the Nox cat as both solutions are fooling the ecu in different ways..

So which would you advise/recommend Will? I've already deleted the secondary cats with the Direnza pipe as you advised!
NOxEM and Maptech NOx delete both cost about the same! Just not sure which method to go for (reliability, efficiency etc.)
Maptech charges £70 extra for a rolling map for the 330i which although don't add much I think it may improve the throttle response!
