hi can anybody help me please ive got a 2wd saff stage 1 tune seems to have developed a misfire just under 1 bar boosti have put new plugs in its not so bad now but still misfires a bit further up the revs.At a guess i,d say its the ignition coil but not 100% sure feedback would be much appreciated thanks

 

What gap have you at the plugs? as if std gap then maybe ya blowing the spark out, try0.6 or 0.7 ish.
Cheers steve

 

What plugs are you using ?, if you have not already fit a group a coil, as with this and some AGPR12PP8 plugs you will find it drives much better, especially low down.
It could also be leads if a bit dodgy.
