Advice needed plz

it wont affect the ignition timing on a coilpack engine naz, can you post a pic of the lobes at tdc ?

Did you get it mapped with these cams?

Lumpy cams are called this as the cams are more 'lumpy' and this gives you a lumpy tickover.... But it shouldn't die though...

Mine ran very weirdly without a map when I fitted GrpA cams, seemed to be missing etc but perked up at higher revs...

If they're aggressive cams you may just need a map
