I'll post up in the FS section and look for trades for the stock parts. Should get me a little extra cash. I definately want an IX. I didn't even consider getting a new one when i was lookig for the car. I just figured i could only afford a used 03. Big mistake.

 

Chewie, I wouldn't be surprised if you're already tuned, because that's the only way your boost is higher than stock and holds without tapering, since you don't have a boost controller. This would also explain feeling faster than a stock 05, because the intake and IC piping would definitely not make your car feel fast without a tune.

 

Any easy way to check? Boost doesn't hold all the way to the end. It drops off quite a bit towards 7k

 

Hmm.

You can't really check, because if it's a Dynoflash, it probably was done before he added launch control in December, and I'm not sure which other flashers include launch control on theirs (only EcuTek can do it with other flashers). You could check to see if the rev limit was raised to 7800, but most people can't visually tell the difference between 7600 and 7800, since the tach is not accurate, and because there are no hash marks between 7k and 8k.

 

another thing, I 've been told by this kid in a pretty friggen fast GTI that I see alot that I shoot out puffs of smoke when im goin all out. Would that not happen with a tune or is it possible.

 

It's always possible, but generally happens when rich.

 

Sorry to bust in here like this, but my car revs to 8k. Would that mean that I am flashed? Or could it just mean that my tach is that much off?

 

Well, the stock rev limiter is 7600, so it's highly unlikely that you hit 8k unless you are flashed. It's possible that your tach is just off or that you are seeing the momentum of the needle carry it to 8k. You'd have to sit stationary in neutral then rev it up there and hold it to see if it's really going all the way to 8k, but I wouldn't recommend every doing that. I certainly wouldn't do it myself. I'm able to use my SAFC to check the revs when I need to...

 

Is that dangerous? Or is it running to lean that I should really worry about? heh sorry for all the questions I'm trying to learn all this as much as i can.

 

Haha, no, it's not dangerous. Almost all of us puff out black smoke. Running lean is what kills the motor. Running rich just kills your gas mileage, power, and nostrils.

 

Thanks Warr. I guess it could be the momentum, but it just seems to be at 8 when the rev limit kicks in. Ehh, who knows. I will get flashed in due time anyway.

 

My BOV i THINK is set to recirculate but I'm not possitive. It is very loud and sounds like a sneeze (lol) also it's adjustable but i know nothing of what adjusting it does so I haven't touched it. Is it normal to feel some jolting when letting off the gas a certain way? I think it's the BOV causing that.

 

(this has turned into the Warratalon advice thread :P)

 

The jolt is probably compressor surge from building light boost at partial throttle then letting off slowly. The boost isn't strong enough to make the BOV purge, so it flows backwards to the compressor wheel and has the effect of spinning it backwards. Think of putting the car in reverse while rolling forward. Don't worry...what you're feeling probably isn't that extreme, but excessive compressor surge can damage the turbo. This doesn't mean your BOV is bad. The stronger the BOV, the more likely it is to surge. Some poorly-designed BOVs surge all the time, though, so it's important to understand the difference. My Forge RS will surge if I drive a certain way, because I run 26psi daily and have it tightened down very far. If I kept it loose, it wouldn't surge as much, but it also wouldn't hold my 26psi as well either. So, I just change my driving habits by doing a complete lift of my foot if I've built a little boost and need to let off the gas. Doing a full lift allows the BOV to purge even at low boost. This is mostly an issue in higher gears with more load.

Go try it. Put it in 5th, then just build about 5-7psi with part throttle and slowly let off the gas. Your car will buck and jerk. Then, do it again, but this time let off the throttle completely all at once. The BOV will purge cleanly...

 

Aha, I have the Perrin and it has a big silver knob on one end. What does that change? Is it possible to change it so that it doesn't damage the turbo? This is what the Perrin site says about the BOV

"Blow off valve spring tension and blow off flow rates are independently adjustable. Users can independently control blow off valve reaction time and the volume of air expelled when the valve opens.

No tools required. Simply twist the outer, top cap, to increase or decrease spring tension, adjusting blow off valve response. An internal adjustment controls the airflow rate while venting boost pressure. The added adjustability allows the tuner to vent less air for low boost applications and more for high boost applications. Custom tailored venting will minimize your boost lag between shifts."
