jims13 6 Posted October 21, 2010 Report Share Posted October 21, 2010 ha you said there ' new plugs ' regap them , as the standard gap will not workj if you are running more than say 8 psi Link to post Share on other sites
jims13 6 Posted October 21, 2010 Report Share Posted October 21, 2010 mine are gapped at .22start reducing the gap on the plug until you find one that works. Link to post Share on other sites
trix2702 23 Posted October 22, 2010 Author Report Share Posted October 22, 2010 Already gapped at .22, With further inverstigation, the boost is fluttering between 15 and 20 psi, can only assume a fault with the wastegate, have a tial to go on it so hopefully this may cure the problem8-| Link to post Share on other sites
