well i have my 2.9 zzp pulley and and the smaller belt. my question is can i install this with out a tune and be fine. or do i need injectors with a tune. cause i now if u get injectors u need to get tuned. but with the stock injectors i dont now if it could handle that pulley.

 

yes you need bigger injectors for the 2.9, dont put it on unless you plan to get 42s or 60s.

 

ok i just wanted to make sure thanks
