My money is on wiring messed up since he's getting a code for both sides.More than likely you got a wire crossed up or a weak solder joint.
No. You will just have 4 plugs that are left unconnected.If locking out the flaps and turning off in the tune, is any rewiring still required?
Not yet. I did a before dyno with only CAI and exhaust and put down right at 390 wheel. Now I’ve added the 18’ manifold and Lund flex tune so we’ll see what the gains are. I’m not sure when I’ll get back to the dyno but it’ll be in the next few weeks. I’m hoping for 440-450 whp.Do you have Dyno results for the OP install?
The vacuum port in the back is just a pass through to the vacuum port in the front. You can leave both those ports alone and block off the port coming from that distribution block instead.
The vacuum 1 ports on the front and back of the intake manifold can be left disconnected and uncapped as they are interconnected with one another and nothing else.Is there any way you could do a schematic for this? I just switched to the lockouts and wasn’t aware the vacuum lines changed
