I was just wondering if the EMS ever loses it's tune after about say 6 months. I'm thinking it's a vacuum line but I can't find any loose or off. I've had a Vacuum line come off before and the revs went up but it sounded different. My Revs always use to be around 1900 rpm but now they studder there for a second when I come to a stop and raise to 2600 rpm to have the correct A/F ratio. I have a wide band with it so I'm wondering if it is correcting itself since it won't hold at the normal rpms anymore. OR hmm maybe I need new injectors? ugg it sucks. All my other mods are in the sig...Thanks

 

go to home depot get some pvc pipe a silicone coupler to fit the end of the PVC and your turbo inlet, Put a ovc cover on one end and seal it. Go to your local wheels shop and get a tire valve stem. drill a hole in the top of the pvc cap to fit the stem. attache new piece to turbo inlet.....


close off any obvious openings where air can escape, hook the air hose up and turn the air on... now listen for leaks and theres your vacume leak.

 

Did u ever figure out what was causing your high idling?

 

1900 idle? wow that's high

 

Yeah I figured it out....very VERY crappy tune. After we started over from scratch the idle is now at 1400 and the revs are so much smoother.
