im jus saying 600 is cutting it close to abnormal. imo normal would be closer to 650

 

My sedan has always idled between 550-650. More 550 after a long drive of 1 hour or more.

 

that's nuts. at 600 my engine is intermittently shaking already

 

Maybe it has to do with my tune and mods. I specifically asked my tuner to set my idle at 600 as that's what it's always been. My car seems to like it.

 

interesting

 

Yes I used the pedal dance for the re-learn. When you change a part like the TB the engine and computer need to "learn" how to get along with the new part. Doesn't have anything to do with Osiris.

 

What are your initial impressions of the driveability of your car now that you've driven it with the new TB?

 

I am impressed with the improvement in overall driveability. Throttle response is crisp. It revs through the RPM range much smoother and more linearly. Whether or not I gained any HP I cannot effectively say, but it is definitely more fun to drive.

My only concern is how this mod (if at all) has affected my air fuel ratio, but I won't know until I go for a re-tune in the near future.

Tim, does your TB whistle at certain times? I'm noticing at certain throttle positions I get a faint whistle. I've checked for leaks and found none. Everything is buttoned up tight and idle is not affected.

Stand by for fuel economy findings. Will need about a week for the ECU to get used to the mod.

 

No I haven't noticed the whistle sound, just the improvement in driving satisfaction you mentioned.

 

I suppose it's possible that what I'm hearing is my Stillen intake sucking in extra air.

 

Is the noise 2700-2900 RPM?

 

And my idle by the panel is ~800? Should it mark at 600?

 

I think the whistle is more in line with throttle position and not RPM. I will confirm on my drive home today.

OEM idle is 650 +-50 You're out of spec at 800. Just make sure it fits within the perimeters and you'll be fine.

 

When I am at 27-29 and go WOT it has a nice whine. That is what I am getting at.

 

Just wanted to update, the whistle is solely based on throttle position. There is no set RPM or speed that it happens. Leads me to believe it is indeed my air filter. I will clean it this weekend.
