ok guys i just put zc pistons+zc rods in my d16z6(reuild)...and a bigger customized intake manifold,i took it for a spin and the damn thing sound like it was going lean lol so i took it to my boy he street tuned my p28 and now it sounds good and rides smooth but i wanted to know if im forgetting something if i am please lmk asap.
thank you for viewing.

 

You needed a tune because of the higher compression pistons. You got a tune (proper tune hopefully) now you should be fine

 

the tune i got is a street tune and it worked good i travel 100 miles everyday so hopefully by thursday ill be breaking the motor in to see how good the tune is....one more thing do i need a aftermaket fuel pump,fpr,fuel rail?
