So I have a '05 A4 1.8T and its chipped with the brand new Autospeed chip put in by 3zero3 Motorsports and I am supposed to be boosting at 18lbs for now and my gauge is only telling me 11 and once I hit 5000 rpms its drops off to about 8lbs but I am having a hard time believing that its a leak because from the time it spools to 11lbs the boost doesnt move until 5000.

would anyone have any idea what is going on.

I am also running a Atmospheric BOV which is coming out and being replace with the stratmospher DV. So do you think that running the atmospheric hurt my boost level? I have been told it has thats why I'm switching over to the recirc.

did you talk to the guys at 303?

They might have a pretty good idea on whats going on....

yeah trevor and i are good buddies im going up there tomorrow but i just wanted to get some opinions on what you think im convinced its something the do with the program for sure cause they had trouble getting it to take for some reason but i really think i made a mistake going with autospeed i should have just went with revo knowing that its a really good program

Well it's a AUDI and a 1.8T and as the saying goes around here your pretty much fucked

Luckyy · « **Reply #4 on:** July 06, 2009, 09:56:28 PM »

might check rotary changeover valve, not sure when the changeover is (or if it even has a shifter rod...) on a 18T but 5000 rpm sounds about right... Who knows.

Maybe its a loss of power at 5g instead of a loose

Boost leak. That little KO3 is doing its damndest to fight the leak and give you 11lbs of boost. KO3s aren't known for their ability to feed air into the engine at high RPMs and they lose steam in the upper RPM range. If you add a boost leak to it that detriment becomes exaggerated, hence your boost dropping to 8lbs after 5k.

sorry man didnt mean to put the of in there lol

yeah i talked to scott a 3zero3 Motorsports and there isnt boost leaks and nothing is mis firing but i has to do with the air intake getting way to hot so i have to go actual cold air intake which isnt a bad plan anyways and the program needs a re-flash and to be tinkered with a little but thats what the deal is and the k03 turbo can handle about 22lbs max and scotts turbo has been a 20 lbs for almost 40000 miles and he has had no problems but thank you for all the input

Barry · « **Reply #9 on:** July 08, 2009, 06:46:43 AM »

does this happen as soon as you start your car up, and run it in the morning?

If so, I highly doubt heat soak being the issue at hand

3zero3motorsportsAudi · « **Reply #10 on:** July 08, 2009, 03:30:00 PM »

no it doesnt matter of the car is hot cold morning night it happens pretty much at all times its a pain in the ass

Sounds like somebody is trying to sell you a cold air intake

yoogene · « **Reply #13 on:** July 09, 2009, 10:15:04 AM »

sounds like you aren't chipped. And if you are, you're running stock programming. 11psi peak to 8psi fade is normal for stock programming. If you get tuned properly, it should go to 20psi (depending on the tune) and fade to 16-17psi by 5k rpms.

The drop in boost pressure is normal due to the size of the k03 and the fact that it runs out of breath by that RPM range. You should never NEED a CAI on the 1.8T motor in an A4; the stock airbox is actually very well designed and the only reason to get an aftermarket intake is for the BOV noise.

i didnt have the stock airbox when i got the car it was changed to a cone filter its stupid but ive never heard of a stage one program there are things that restrict it like the cats need to be changed to be able to boost 20 and its not stock programing its like revo apr and all that shit its all the same thing really

yokust · « **Reply #15 on:** July 10, 2009, 11:36:34 AM »

You need to have them find the problem, and not buy any aftermarket parts.

Even a dumb cone filter will not cause the low boost problem unless its clogged and not flowing air.

There is either a boost leak, or something causing the boost to be low (boost leak, maf, crankcase hoses, n75, boost sensor)

yoogene · « **Reply #16 on:** July 10, 2009, 11:58:41 AM »

Trust me, you're running a stock programming file. You may be chipped, but your ECU isn't running the chipped file. I thought i was a long time ago, but turns out the program never took on the ECU and i was wierded out until i got a boost gauge and found out what was up.

Get the car back to the shop and have them fix it. Don't buy more aftermarket parts for it because then they're just using you for business. A cone filter def won't restrict your boost unless it's clogged like Yokust said above. If your cats are burned through, you should still be able to get 16psi. If the file is indeed there, you need to confirm that it can boost; if it's not that, you may have an issue with the wastegate actuator or diverter valve.

yeah man your probably right considering that they are taking the car for like a week and re-flashing it and adjusting the program to 1800mbar or some shit lol but they had problems with the chip not taking the first time so it probably didnt take the second either but the weird thing is for like an hour on my way to denver to go to the shop i hit 18 lbs and thats the only time but its just 11 again now so whats that tell me if i hit 18 lbs cause i dont think you will ever hit 18 lbs on stock programing thats the only thing i question and there is def not boost leak ive had everything tested for that shit no boost leak

Did you have it tested at the same shop? It's definitely not the intake, Also the BOV could account for some loss in Boost pressure. If it spiked at 18psi then dropped back down to 11psi, It sounds like a leak to me. I would have the seals checked by a different shop or one of the guys on the forum. But an intake is not going to cause a 7lb drop unless its covered with newspaper and resin.

3zero3motorsportsAudi · « **Reply #22 on:** July 11, 2009, 04:26:29 PM »

yeah no leaks man its hard to explain something is miss firing or something idk fuck it all man but 3zero3 did diagnostics and they are taking the car for 3 days and re-flashing and doing all this shit and making custom files for it the guy that said the chip is at stock programing something isnt reading right in the ecu scott said something about the program needing to run at 1800mbar whatever the fuck that means but yeah he said i need to get CAI to which i was planning on anyways but hopefully he can get it figured out

yokust · « **Reply #23 on:** July 13, 2009, 11:30:51 AM »

Get the chip figured out before you buy anything else.

If and when chip works correctly than maybe buy your carbonio or whatever it is

yoogene · « **Reply #24 on:** July 13, 2009, 06:00:04 PM »

You only got the trial flash. They got it to take, but it didn't' take the right program. I only know this because the same exact thing happened to me 4 years ago.

i did not get a trial chip trust me and i need cold air intake because my shit is getting to hot and it will allow the car to actually produce boost through the chip

No man. Slow down.
The stock airbox is more than capable of producing boost with aftermarket software.

You honestly think a filter on a stick is going to solve your problems? A CAI is only going to change the initial intake charge temp by 10-20 degrees, but the turbo is going to heat up the intake charge to over 200 degrees, negating most of the CAI's benefits. If air temp is your problem you need to change your intercooler to a more efficient one or go water meth. If the intake is your problem it's because there is a crack in the pipe or there is a loose fitting somewhere after the MAF creating a vacuum leak or a boost leak. If it boosted really good for a few hours after you got it chipped, you either got a trial flash or something broke.

BTW, I have some seaside property in Arizona I'll make you a good deal on.

Barry · « **Reply #32 on:** July 17, 2009, 08:22:34 AM »

it's actually called beachfront....

OP.... you should polish your manifold when you put the CAI in.... that would be tyte!

My shit gets hot too, when i just jam it in without lube

Must be whats happening to you
