Hi,

can some tell me whats wrong, i have a gsr with mild built head with stock block. i just install some sk2 stage 1 cam shaft and tested the car after the installment, the car is actually slower than having the stock cams on even when vtec engages. Does it mean that i need to adjust the valve lashes because of the lobes of the cams are too big. please help me i'm at a lost here

 

Tune it

 

U always need to adjust the valves when changing cams for it to run correctly...should def make more power but u really should tune it to make max power
