I'd look into getting the injectors flow tested. I had RPM drop/dying out issues after installing brand new FICs. Turned out one of them was defective.

 

Yes it is but it fixed and issue with the shifts so my oem one was on its way out and it gives me the ability to monitor the fuel pressure which is a def plus since I have a spec ops double pumper or whatever the other brand was that used to make them and I don't really 100% trust it because it came with the car and I don't know the milage of the pumps.

 

I got a used synapse dv and my idle dip seems to have gone away. I had a stock ix crushed dv. I still have random cylinder misfires though.

 

Hmm I got an aps dv and came from a forge, maybe it's time to get the tial I've been wanting. Guess that whole setup will have to be the next part I get to try and fix this issue, or just play with the adjustment knob and see if that helps.

 

So I have the same problem and a custom intake... thinking that air from the bov is possibly getting reregistered..?

 

Look at this thread I made guys. Noticed something weird about the dv setup.

I don't think so mine is well after the maf and I still have the same issue, I'm trying to chase it down and shaesta has his fixed with his new synapse dv. I just replaced my fpr, injector seals and the fuel rail didn't fix it but I did find a good boost leak at the biss screw. I got a new one n tb gasket on the way. After that if it doesn't fix it I'm gonna try a tial dv and then possibly a new tb since I cleaned the grey goop that seals the butterfly.

 

Ok let me know what you determine. I have the Tial QR on my car with a white spring in it currently. Just don't understand this, I feel your pain I changed so many parts and tried so many tests and just can't get rid of this. Do your A/F ratio go rich for a split second after shifts as well?

Ay homie, spend some time reading this thread... I'm gonna play around with some things and let you know.

 

Yeah it could end up just being a tune issue, that is one of the possible fixes for this but I wanted to replace most these parts anyways so I'm just going through each one one at a time so if I do find it's something besides the tune I can finally say for sure the issue for someone else down the road who has same issue. And yes mine does peg out for a little with the clutch pedal pressed in.

 

It makes sense. I'm going to pop the oem dv off my buddies car and see if air is coming out at idle. If it is I'm going to go with a lighter tial spring and different suction pipe and get back to you. I have to say it's rather reassuring to have someone else that understands my pain haha.

 

Yeah from what I can tell it's actually a very common problem but nobody really posting a final say so on the fix when they do fix it, lemme know what spring you end up with so I got a good place to start when I get a tial. Until then I'll jus play with my dv , it's adjustable so I may find that it will work. Just been busy tracking down parts. ( all the mail services decided to start losing my packages) and throwing on some seat lowering brackets. ( wow do they make the car feel like a whole new car). But if FedEx can find my package tomorrow then I'll be putting on a ps pump with sensor to try that theory and sometime next week should get the new biss. If those don't work it's down to mystery grey goop in throttle body, dv, and tune. Hopefully eventually I'll get to the bottom of this, and stop posting such long winded posts haha. sure wish they had a shot of vodka icon haha

 

I had a leaking biss screw. Replaced biss and o ring and it didn't change. I have a littke of tge Grey stuff off my tb but most of its still there.

 

yeah my tb isn't doing the same thing that most people complain of without the grey stuff( my idle is relatively normal) but I'm gonna fix it anyways. And my biss is leaking something fierce, only reason I hadn't caught it till now is its so close to the loud engine so that needs to be replaced if for no other reason than to seal another boost leak.
