Leaning out under boost
I am just finishing my 930 and I am noticing under boost lack of power when I really get on it. I installed a lean rich gauge and it shows a lean situation under hard driving. My fuel distributor is new as well as all injectors. Is it possible the injectors I install are to small volume wise ? Is there a fuel pressure gauge I could install on my dash to see if thats the problem ? I also have new acumulator,fuel filter.
