I had installed the Forza Controller on my 360 when I first bought it almost 2 years ago. The controller works well as it should. I would start the car in normal mode, meaning the valves would open at start up and then close a second or 2 later. I could use the remote buttons on the fob to then open or close the valves at any time. I recently installed a 430 muffler with exhaust pipes with valves on my 360. Now when I start the car the valves do not momentarily go to the open position and then close a couple of seconds later as they operated previously. The fob however does work and I am still able to open and close them without issue once the car is started. I'm trying to figure out what coud cause this change in behavior. The original hoses that go to the 360 valves are too short so I had to replace the length of hose that goes from the solenoid to the exhaust valves as the valves positions are now further away towards the muffler. The original hoses on the 360 have a very thick wall, and I was not able to find anything similar locally. The hoses I installed going from the solenoids to the valves now have a thinner wall. I am thinking is it possible that on start up the initial vaccum draw on cranking is higher and collapses the hoses? I also recently got a P0411 code pop up pertaining to "secondary air injection system incorrect flow detected" I can hear the air pump running, after investigating, although to tell the truth I never had noticed the very faint high pitch coming from it until now when I was listening for it to see if it was running. Could it be with the valves not opening on initial startup that the flow is restricted causing this error Code?
