Dunno whether this shouts fuel or ignition at ya, not asking for a definitive answer but just a few nudges in poss directions.
Scenario - me Cav T was running well but hesitant at full throttle, reduced plug gap down to .8mm and it ran even better and felt good at full throttle too. So all is fine and dandy, did bout 10miles on sunday like this and all was good still.
This evenin, went out for petrol and chocolate run, runs perfect on half throttle up to bout .7bar boost, as soon as you hit .8bar seems like its missing, bang the throttle and it overboosts to near enough 1bar and it kangaroos, when settles to .8 again it still misses, pops and bangs, not nice.
So any tips?
BTW, leads, plugs, dissy and rotor all replaced 40miles ago.
