The Vac isnt that difficult but it can be confusing to just read it.

I would grab a few feet of both 5/32" vac hose and 3/8" vac hose along with an assortment of fittings (elbows, T's etc) They usually come in variety packs. You can re-use some of the factory vac hoses as well. Zip ties around everything isnt a bad idea to avoid vac leaks.

Keep in mind the nipples on top of the blower only see vacuum, and the ports on the manifold see both boost and vac. The bypass valve, Fuel rail pressure sensor, powercard (if used) and boost gauge (if used) want to see both boost and vac, everything else only sees vac.

thats the bypass valve actuator; it gets hooked to a port on the back of the manifold. The boost guage can be hooked to the back of the manifold as well. (there are 2 ports) I have a vac T off one for my boost gauge and fuel pressure sensor (on the fuel rail).

okay i need everyone's help i can get!! I got my JRSC installed and everything was going good, i was doing a remote desktop with tom as we were working on my tune on Friday night. the only problem we were having was that the throttle was sticking. so we left it alone for the night and he sent me a new tune on Saturday morning and told me to do this "For the idle try this , unplug the air idle controle valve , start the car , set the idle screw on the TB to about 750 rpm , plug the idle air valve back in so i did. i also unplugged the TPS when i plugged them back in the car would no longer run at all.. the only way i could get the car started was to crank it and hold the throttle open then the car will start and idle at 2300 for approximately 5 seconds and then dies. it also is burning a lot of gas doing this i mean to the point where i pulled a spark plug and i could see all the smoke in the chamber from the gas.. i have gone over the whole install many times, i have checked the vacuum lines, electrical connections, and i have even replaced the TPS and it still will not run other then the 3 seconds with the throttle open.. i am in complete loss for what is going on. anyone have any idea????

is you're iacv functioning? If it's stuck closed it could be choking out the engine. I ask because you say it will run if you hold the throttle open a bit.

i am in the process of replacing the IACV now. i think that might be the problem because the one i pulled off doesn't look like the new one. looks like it is stuck shut.

I replaced the IACV with the one that came off of the stock intake manifold and put it on the SC and it idled perfect for about 35 mins. then i shut the car off to change the tune to a drive tune and when i tried to start the car back up it wouldn't start again. i pulled the IACV back off and checked it out, it doesn't seem to be stuck shut like the other one was but maybe it is stuck open now.. i really don't know.. i am going to get a brand new IACV today and try that hopefully it will fix this problem,... sorry i couldn't make it to FF this weekend i had every intention of being there.

so as the car sits right now i bought a brand new IACV and it has been redesigned and the plug is now at a 90 degree angle and will not fit, so i went back to the parts store and took my stock IACV with me and one of the guys working said that the IACV off of a 1998 mustang and a ranger were the same as mine. so i got one and put it on with no success. any one have any other suggestions to what could be going on??
