So i installed a boost gauge today...

[JettaB.Ont]

took it for a spin, and to what i thought 2 months ago was a stock gli that i had purchased from an older owner (about 40) Seems to be spiking at 20-22 psi and holds around 15psi.

So i drove my friends stock 1.8t and it defiantly doesn't pull as hard... but not by much. I also noticed i can hear the turbo a lot more in my car when it initially starts to spool around 2k rpm.

Since i was planning on getting a chip in the future.. my question is, is there anyway to see what kind of software the car has ? Cause i mean, i wouldn't want to go spend $500 on a chip, when its gonna do the same thing.

i have ur same issue. i took the ecu out and looked on the circuit board due to uni not being able to load. talk to the previous owner and ask him.

[JettaB.Ont]

i did, hes like wow really? not to my knowledge.

he said the original owner used to work with him at vw.. but he doesnt any more or he could of asked him.

[05GTIMarine]

if he knows the original owners name then you can track him down. well worth it. i found out that i have apr stage 2 on mine. good thing i didnt switch to uni.

my mothers 60+ year old girlfriends beetle turbo is flashed with giac x+. youd never know by looking at her, or the car.. a ton of old people flashed their 1.8t's.. id say a good percentage of them on the market used are flashed

"stock doesn't pull as hard, but not by much"

APR? Def not UNI...

This is only true if you have an AWP.. for all others the flash is night, and day

well what do you mean for the awp. is it because stock psi on the awp with a ko3s is 11 vs. ko3 and 8.5 with other blocks.

[dubinsincuwereindiapers]

you got it.. for example.. my aww is litteraly identical to the awp in every way except the tune. ko3s, wideband, vvt, everyhting. but the aww only has 150hp from the factory because of the tune.

[05GTIMarine]

i wish i new how to write tunes. oh well.

[Scrambles]

yah, im gonna call around with my VIN and check it out, b/c i spike 17-18, and hold 14-15;

we'll see, maybe i'll crack open my ecu

[1.8Tjettta01]

take it to one of the chipped dealers thats closest to you, they should be able to tell you if APR is loaded or UNI, or revo or eurodyne or giac. go ask, it doesn't hurt.

if you are boosting above 15pSI, you are chipped no doubted. or software flashed which is more than likely. don't waste your money.

[01TornadoWolf]

cracking open the ecu is a waste of time seeing as the "chips" are just software changes. nothing to see.

Hahaha, yikes, those poor 1.8T's. Some things you just can't unsee, eh?

If this has become more apparent over time, I would inspect your downpipe. You may have a leak or cracked DP. That would explain why it doesn't pull as hard as you think it should.

Why would a post turbo exhaust leak hurt performance?

I need to get those two 1" leaks fixed on the back of my car!

Anything pre-O2, even post turbo, can cause performance issues since the primary O2 is getting false readings. Once past that primary O2, a leak won't hurt performance.

My flex section is currently cracked and was running rich as hell, have terribly slow spool (stock turbo), and the spool is very audible even at 0-5psi.

[Buschwick]

I know this isn't the topic....

Why would it slow the spool down?

It's a symptom of running rich. The overall motor doesn't feel as strong when running rich, so turbo spool my just be an indirect symptom.

i had the same problem with my car when i bought it, i tried out a brand new stock ecu and it pulls way less, so much throttle lagg. This one spools and kicks way faster and exhaust has a different sound. I think fuel timing musta been edited also.

I really want to put a boost gauge on to see what im at because it seems way faster thens stock.

isnt the turbo a little different too? pretty sure it is and now that i think about it, i remember hearing the connecting rods are stronger in the awp. could be wrong tho

[JettaB.Ont]

Thanks for all the help guys.

Note i got an AWP cause i have an 04.5 GLI..

Upon driving it to school today and back, i discovered i hit 22 psi max and i hold ~18-20 and it drops off to around 15ish in the high end revs.

The turbo spools quick too.. i can make a video if needed, and its always been this loud so i doubt an exhaust leak of any sort.. cause my car is very quite.. and id assume an exhaust leak would make it a lot louder.

I called a place, and he said he will check it out free of charge.. so thats a good thing.

[Cryser]

call all the various tuners with your vin they should have a database of cars by vin that have their software tune.

also your waste gate it probably cranked a bunch try backing the nut off a few turns.

[JettaB.Ont]

upon even further driving on a backroad.. i gave it a 1st 2nd and 3rd.. and and it boosts at about 15 psi steady..

if i do a 3rd gear pull i hit about 20psi like i said.. and drop to about 15

Also .. about how many inches is suppose to be before the rod on the waste gate rod.

[Cryser]

you can either look with a flash light and see if you can see a difference in the threads (one really shiny 1 not so shiny) OR just unplug your N75 and if you can hit more then 5 PSI then your wastegate is cranked, uncrank till 5 PSI

[JettaB.Ont]

i know this threads ancient guys..

but i went to the shop, and he wasted my time.. told me he would just flash my car for 500 bucks then id know what i would have.. i said no thanks as i would probably feel minimal differences.

a few year later.. fast forward to about 2 week ago, i start looking for a fuel pressure regulator.. i call everywhere saturday cause i wanted a little edge on my friend who just bought a chipped 337, anyways, a guy and this very reputable thing shop says he can get the 4 bar from the passat motor he has had there for years.

he tells me to check what i have just to make sure it was a 3bar which comes stock.. low and behold.. stamped on the side.. 4 bar bosche fpr..

so i now wonder if my chip is one of the few which support a 4bar.. also since getting an exhaust, and having the car pushed farther down stream.. i spike 19 psi 2nd gear, 3rd 20, 4th 23ish..

planning on getting an intercooler and going stage 2 in the spring of 2013

[usherboy83]

if you have a 4 bar fpr i really believe u are already at stage 2...i would put a fmic on and enjoy
