Hey guys I recently did a LS-Vtec swap with a b16 head GSR cams with Vtec lockers and b16 pistons. I got the car tuned after the swap but my idle is bouncing from 1.5 - 2k almost all the time. I was thinking it was because of the Vtec locker cams but I the tune was more of a "safe" tune and I was told it would Idle at around 1k all the time. Does anyone have any ideas on what it could be? The car has I/H/E as well on e85 fuel.
