The clutch you would know because if you go pedal to the metal and you read full boost but the car does not move then it is the clutch.

The vibration could be a ball joint or sim ply engine mounts or loose engine mounts. Also, there is always goin to be vibration, the whole cabin will shake do to the extra powa running boosted.

 

i think the biggest question here is what kinda shop returns a car with loose ball joints and a violent shaking??????

 

No it was fine before the conversion and no that axle was thrown out and new axles are in with new ball joints but the problem is still there.

all that has already been triple checked for.

The car started doing this two days after the tune.

 

You might want to make sure that your suspension bushings aren't torn all to **** your axles shouldn't be pooping out of the transmission.

Also its possible that you might have some damage to part of your clutch setup causing this.

 

pretty much everything suspension related has been double and triple checked. the only thing left to do is to change the clutch which i ordered already but now im thinking what if its something else? what else can it be that makes the front end shake so violently that you can see that dash jump up and down literally ? after a shyt ton of money, time and effort, this car keeps finding new ways to **** me off.

 

I bet you its the inner cv boot on the driver side. Before i had my car dynoed it shook crazy left righ up down while accelerating then when i hit boost it was shaking so bad i though a lug nut or 3 was loose so jacked the car up and went through the gears i could feel the vibration took the axle off it looked fine then opened up the cv boot inner one and it had small shavings in it cause it broke and was just spinning freely!

 

so i just did a wot in 2nd gear and nothing happened but when i did it in the 3rd gear, it happened again.
clip of the 2nd gear pull

 

you get it fixed?
check tps see if screw backed out a little letting it move.
wont throw a code but will cause violent shacking from time to time.
i had similar problem.
been couple of months but hope this helps.
