mk3_matt 21 Posted April 12, 2015 Report Share Posted April 12, 2015 Hi guysI've just installed a turbo on a friends vr6.I fitted263 cams3mm spacer plateArp head stud kit440cc injectorsFront mount intercooler and pipe workMy question is why does it now run so rough, it's miss firing and won't Rev up.I re checked the timing today and I noticed the lower inlet manifold had little puddles of petrol in it so I changed the injectors to 315cc ones that came with the turbo kit it idles a bit smoother but still won't Rev up.Is this down to the ecu not having a map for the bigger injectors.I thought I would be able to run the car on really low boost till it gets mapped.Maybe I'm wrong. Could someone shed some light on this please.Many thanks Quote Link to post Share on other sites
