notfub Posted December 21, 2011 Share Posted December 21, 2011 I'm about to fit an aftermarket exhaust to my 55 plate zed. If I also add some berks HFC's at the same time will I run the risk of running lean on the standard map. In due course I'll put a plenum spacer and get an UpRev remap but want to make sure all will be fine should go for the berks now? I'm also running the 06 airbox mod and apexi filter too. Thanks for the advice Quote Link to comment Share on other sites More sharing options...
Will370z Posted December 21, 2011 Share Posted December 21, 2011 Best to pm mark at abbey, he highlighted this issue for me when i added berks hfc and the car was running very lean, mind you i had already had an uprev which also meant the car was leaner than stock.

coldel Posted December 21, 2011 Share Posted December 21, 2011 Was in Abbey last week, I had a Milltek, spacer, berks on the car and it was running very lean before the uprev Quote Link to comment Share on other sites More sharing options...
dragon Posted December 21, 2011 Share Posted December 21, 2011 For what its worth you might as well fit the berks at the same time, but get the spacer and uprev as soon as afterwards Quote Link to comment Share on other sites More sharing options...
notfub Posted December 22, 2011 Author Share Posted December 22, 2011 Thanks for the advice and confirmation guys, might get the berks (as Tarmac is doing a good deal @ £375 delivered) and store them until I get the spacer and UpRev Quote Link to comment Share on other sites More sharing options...
Madhatter Posted December 24, 2011 Share Posted December 24, 2011 Oh that's a cracking deal from Tarmac! Think I'll be saving like mad over Xmas and giving him a bell Quote Link to comment Share on other sites More sharing options...
TomS Posted December 24, 2011 Share Posted December 24, 2011 When I got the Berks fitted post UpRev, when I had the car remapped I was told it was running very lean so the Berks have a fair effect! Quote Link to comment Share on other sites More sharing options...
ashyk36 Posted December 24, 2011 Share Posted December 24, 2011 sorry for being dumb but what does running lean mean? Quote Link to comment Share on other sites More sharing options...
Zedebee Posted December 24, 2011 Share Posted December 24, 2011 It's to do with the fuel/air mix ratio.. To much fuel = Rich To little fuel = Lean Or thereabouts Quote Link to comment Share on other sites More sharing options...

FUG Posted January 12, 2013 Share Posted January 12, 2013 I've been told (not necessarily a reliable source lol) that my car may be running a bit rich as tail pipes get dirty very quick and fair bit of smoking from them (although is cold weather at the min) I have pop charger and milltek exhaust system on the car , any advice? Is there a way of testing whether car is rich or lean or is it something a a garage can only check? Thanks in advance Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted January 13, 2013 Share Posted January 13, 2013 the exhaust tail pipes always blacken this is no real test of weather the car is running rich or lean as when the car cold starts it will blacken the tail pipes. Running Milltek and pop charger will normally not mak any difference to fuelling but the cars really needs a run on the dyno to check AFR to ensure everything is running correctly Quote Link to comment Share on other sites More sharing options...
