i installed a skunk2 IM and now the VTEC dosnt pull as hard and it seems to come on and off. its like it will engage and disengage all the way to redline. i also have cai/h/e so everything is free flowing. any ideas??? thanks!

 

what engine?
also vtec engagement depends on manifold pressure, if there is a leak it could make it go on and off

 

any CEL codes?

 

its on a b16a2 and i am not having any check lights come on the car runs fine its just the vtec pull from 5,600 on up is on and off
