The problem I'm having now is that apparently the recommendation is not to upgrade the fuel system for a basic A2A system...but Topz says to upgrade the pump. Then, apparently there is a recommended adjustment (?) to the tophat (?). And finally, an idea is being floated to upgrade injectors with no other upgrades, if I am understanding correctly. Can a larger injector manage the same spray pattern as a lower-flowing stock injector at the same pressure? Could a larger injector cause driveability issues at lower RPMs? Will a stock injector deliver enough fuel at 6-7k and 9psi?
