boosting help please
ok... so i have the profec b set all the way to sharp... and i set it to 15psi in 5th gear... now if i set it any closer to the mild side it doesnt boost as smooth... but now here is the situation.. set at 15 psi i can only get 10psi in 1st gear but right as i shift into 2nd it boost to 15, 3rd, same then it dies off to 10 which it is supposed to... so question is why cant i get 15 psi in first gear???
