Does anyone else get like a plunger noise when tapping the throttle then letting off? It almost sounds like something trying to open or close. Its hard to explain and you cant hear it on any vidoes I have done. It wasnt there before and even now after the LMS tune the car seems to not pull as hard. I tried to reload the tune to see if it would correct it but its still there. Im stumpped. I looked at all of my connection, hoses, tubing, BOV,s and so on. If I can I will just go to Livernois but in the mean time I was hoping you guys had any ideas???

Clicking noise???

can you record it and post as a video….
If it's a click, especially if your performance is off a bit and it only occurs in driving (not just revving), it may be a faulty solenoid on a BoV
Hearing the sound or hooking it up to an OBD2 reader are a couple of suggestions …Autozone and a few other parts houses will hook you up if you don't have a reader.

Good start!... If they don't hear it I'd look at the BoVs since they won 't function sitting still revving as no torque needed.

You can fab a boost leak test kit very easily. I made one years ago for my Mazda, and used it a couple months ago on the SHO, after reading a few owners mention the possibility of poorly clasped clamps from the factory.
An air compressor and a few parts from the hardware store. And a spray bottle full of soapy water (snoop).
I can add more details, if you're interested, or just do a Google search. Any turbocharged car owner ought to have one, and make it a regular checkup.

Thanks guys. I will have to keep a eye on it. I did another video to test performance. I compared A video I did when less than a 1/4 tank and a video with a full tank. I filled up and didnt drive it for a few days. Maybe im just used to the power already and after filling up it seems like power loss. Im still not sure about the noise though. It almost sounds like a N/A car sucking air when tapping the throttle. I dont know maybe I just didnt notice it before. The best thing I can think of is to have someone around me that has had there SHO for a while hear it in person. In the videos I have done you cant hear it.
You could also try running 12 oz Techron Concentrate Plus Fuel System Cleaner with 10 gallons of premium gas for that loss of power you feel, works wonders for $7-8 locally and everyone carries it, link below.

Its gone now. I turned it back to stock then retuned it. It seems to pull a little harder now. Im going to regap the plugs as well. I havnt done it yet. I hope that will help. Im curious to see how far apart they are.

Will do... I just have to find time to do it. What kind of difference have some of you guys seen? Any change in performance/smoothness?
Changed my plugs at 33,000 with SP-534 @.30 and didn't notice any performance gain. I did notice that it helped my car idle and drive a little more smoothly.3POINT5 said:SHOdded said:Post pics of the plugs also, please!

Glad your click is gone. Maybe the tune didn't load quite right. The new plugs might not show a real noticeable difference but, they will aid in the overall smoothness of the engine and gapped properly, they will be safer at high rpms.
The car is running great now. The mid 2000's mustang found out how great last night. It was loud lowered and suposedly not stock. The guy even picked the fight. What he didnt know was I had the stage 4 tune. Man it wasnt even close. The next light I asked if wanted to go from a roll since I have AWD and he declined. I told him maybe next time as he drove away...
