Take it back to the dealer and make them correct whatever is wrong. If it was fine before you took it in, than there is always a possbility it has to do with the work they did, especially if they have replaced the tps and idc.

That BOV and intake aren't helping. Both of those HKS parts have been known to screw up idle a little. But if it was working fine before something got screwed up. Maybe the idle adjustment screw.

I have the SSQV and its VTA does the same thing. VTA= bad idle.... it sounds better but runs like crap. Mine doesnt drop idle all the time, but same result. Sometimes goes lower then 750 and almost dies.

I would try readjusting the eids... and if that doesn't help take it back and have them re-calibrate the TPS

Being VTA doesnt affect idle unless the SSQV is broke. It only affects you when you lift and actually VTA.

If you are willing to make the trek down here to have us work on it we can solve the issues all at the same time.

+1 on that, HKS intake does nothing to idle as well. Adjust your idle up to 1200 that would help and will smothit a bit, but will not cure it. Its tps messing up, just gas it up if it drops.

....Oh what does that cost to fix? Mine has been doing it since i put the SSQV on. Lucas turned the idle up a bit when he tuned to try to make up for it but it has always bogged down every now and then.

Well if it is a tune...then my guess is you will run like mine after. Which is when you make a stop after med-high rpm's then you will bog down. But if you do get it fixed somehow let me know. Lucas told me that it was cause im VTA its gonna idle rough. And that was said after both tunes. GOOD LUCK

And yes the do a good job on the tunes. They come up for the dyno day in Auburn

Saturday May 9TH

Where: Drift office @ Auburn (at there new shop)
1535 Auburn way North
Auburn WA, 98002

Dyno Jet AWD

TUNERS: Lucas English and Aaron (JohnBradley)

Time: We'll start at 11:00 AM

Please note that pricing has changed for this dyno day. The prices we had been using were based off of 3 pulls. Everyone at the dyno day can attest to the fact that almost no car was limited to three pulls. The pricing structure is being changed for this reason.

Going from a stock turbo (8 or 9) to a bigger turbo, will put you into the new tune category.

Dyno price for new tunes will be $100
dyno price for retunes will be $60


Retune – 100
full tune- 200

Additional charges
Add meth - +50 (250)
Add larger injectors- +100 (300)
Add both- +150 (350)
E85- 300
E85 and limp home gas map- 450
AEM- 500
DSMlink- 150
SAFC/MAF-T- 80

Spark plug covers and undertrays must be off before you get on the dyno! There have been alot of people the last 2 dyno days that have not been listening to this warning. If your undertray is not off there will be a nonnegotiable $20 fee to remove it and another $20 to reinstall it.
