High Idle After Clutch Install....?!?!?!?

[TantrumSKID]

I just went to Turbotrix in NJ to get my SPEC Stage II put in and everything seemed to turn out fine. The gears were stiff at first but after some shifts they smoothed out and the clutch grabs very nicely and is surprisingly quiet. My only issue is that now my car idles at 1250RPM with the engine fully warmed up. I can not for the life of me figure out why a clutch install would affect my idle status. The first time I noticed this, I brought the car right back since I was only a few mins away and the guy took a look at it. He fiddled a screw at the top of my motor (which I'm assuming is the idle speed sensor adjustment) then he thought the recirculation adapter fitting on my HKS SSQV felt loose. Long story short we reclamped the hose and everything SEEMED fine. My idle dropped back to 750 or so and I was on my merry way. From the shop all the way to the highway, each stoplight was A-OK. Idle stayed a steady 750. After reaching the highway and being used to a very badly slipping clutch for the past few months, I naturally wanted to get on the throttle and feel again how my DSM should pull. I didn't do anything too crazy, just wanted to make sure the clutch was doing its job and in every gear I floored it to about 5500RPM before shifting. Once all seemed kosher, I took it easy and did the speed limit home. Now here's where it gets weird (and if u're still reading after all this babble, I gladly thank you for your attention). After I got into New Yor City, the stoplights started becoming plentiful and naturally I had a lot more stop 'n go due to them and the increased traffic. That's when I noticed surely enough my idle had returned to 1250RPM. I was in medium to heavy traffic until the final stretch near my house where I was again on the highway for a short time. The last highway I was on has very poor road conditions and the paving is bumpy to say the least. Ater driving through the uneven road and enduring some rattling I got off the exit very close to my house. Here's where things get EVEN WEIRDER. Somehow that rattling and shaking must have impacted the problem source as when I finally pulled into my driveway I noticed my idle had lowered to a steady 900-1000RPM. If anyone has any kind of insight or has personally done a clutch themselves who can see a potential problem or slipup that the Turbotrix mechanic might have made, please feel free to help me out. Thanks so much for your time.

try changing your BISS screw and the o-ring...see if that works

just adjust the idle again it takes a few tries to get it right make sure the cars warmed up when you do it though
