is it just me?

is it just me or does anyone have this issue. i have a UR turbo back, manual boost controller, forge BOV, K&N drop in filter, and its dynoflashed. i was thinking i wanted to get a bit more power with full driveability so i got tried an AEM intake. The intake makes my car so much louder! (not a good thing for me) Also i have fluttering issues with my Forge BOV. (tried every damn combo for springs and shims).

I'm guessing not but would a re-flash help at all with fluttering or bucking issues?

I want a car that i can drive comfortably everyday. so i was thinking of using the AEM filter with my stock rubber intake pipe. What do you guys thinks???

i took out my intake and put my stock air box back on. much nicer for me.
i was thinking about getting a HKS 264 set of cams. would this hurt my everyday drive to work in downtown L.A.???
help guys

is there anyway you can adjust the bov? for a better drive around town, i suggest p&ping your o2 housing and exh. manifold. there is a excellent write up about it.

I've said it a zillion times: I would not use any type of intake-on-a-stick with any car using a MAF/VAF sensor. if you convert to MAP only, or the car came that way originally, then great.

but otherwise it's a sure fire way to get a car that performs like *** at part throttle. when you see someone saying they can "tune" around it with a flash or whatever, that is only at WOT. it still will run like *** at part throttle especially in varying throttle conditions. deleting the airbox robs the mass air or vortex air sensor of the stability it needs and allows reversion across the meter. air is supposed to be measured just once-- same problem with a MAF/VAF when venting to the atmosphere.

My HKS RS does not flutter or buck. That is not the cause. The MAF has LONG vortices before the sensor to smooth the air. It makes no difference what is before it. The problem lies in the Forge BOV. Putting you stock intake on probably made it quieter and seem more gentle. You also probably work the throttle differently now and not so much with your ear. The stock intake makes you a smoother driver. Get an MR diverter valve or the stock one and it will be better. My car with the will do a little buck at very low RPMs with my foot on the gas but guess what. I figured out that I was going slowly over tiny imperfections in the parking lot/road and my foot was actually jostling the pedal just enough to fluctuate the RPMs. So now I either give it more gas or idle around. It is smooth as butta! Another thing that contributes is the fact that I tightened my throttle cable to where there is minimal slack. So now every little tap counts.

The flash is supposed to be redone when you get an intake. That is considered a major upgrade, especially on a car with some mods done already.

To get the Forge valve to stop fluttering, you have to let off the throttle suddenly so the valve dumps the air all at once, instead of in bursts.

While we are on this topic, does anyone know if it hurts the car to when it bleeds off the pressure in bursts instead of one big dump?!?

I have always been under the impression that the flutter is compressor surge. Please correct me if I am wrong. The stock recirc. valve sounds good and is not rediculously loud.

I have the AEM intake also. I have never really felt any difference from it other then the fact that the car revved a little quicker. After I get my custom tune from Al I will give impression.
