bmx045 Posted January 25, 2012 Share Posted January 25, 2012 what mods does your friend have? looks like rich trim, vac leaks *normally* cause lean trims Link to comment Share on other sites More sharing options...

bmx045 Posted January 25, 2012 Share Posted January 25, 2012 who's tuning it? if everything is tight, ie hose clamps, inlet isn't torn near turbo, all vac lines are plugged, then reconsider your maf scaling. it seems like to me the intake isn't scaled yet Link to comment Share on other sites More sharing options...
RdiggA Posted January 25, 2012 Author Share Posted January 25, 2012 it isnt scaled yet but the First fuel trim is pegged at 25 which is usually vac leak. no point is trying to scale something thats leaking. Plus it throws CEL every once ina while at idle. "System lean" Link to comment Share on other sites More sharing options...
bmx045 Posted January 25, 2012 Share Posted January 25, 2012 informing us about the code would've helped earlier. all we can say is there a leak, so you need to find it before continuing the tune. look high and low, it's quite a considerable leak...
