I just got the APR Stage 1 program installed on my TT.
What a difference. I'm very happy with the results.

 

Where did you get this done?

 

I got it done here:
EUROLINE PERFORMANCE INC
2380 ROYAL WINDSOR DRIVE SUITE 14,
MISSISSAUGA, ONTARIO L5J 1K7
The guys were really good and there's a sale on APR stuff right now.

 

any idea what kind of performance increase (hp, acceleration times, gas consumption). did you do anything else to the car - exhaust?? and what kind of mileage was on car when you did it?

 

Do you got a boost gauge? What kinda psi are you pulling. My TT is chipped, I don't know by whom though. The previous owner bought it that way and did not know much about it. I'm pulling 17psi. There is no signs of the maf mod. I did contact a few company's with my VIN number but apparently my car is to old. They told me I would have to pull my ECU. I've have not been to motivated to do so though. If you don't have a ForgeMS DV yet I would recommend one. The stock Bosch unit sucks.

 

Stage 2 program. Stock TT. It hauls.
Looking for a wiring diagram as I have a serious ground issue with my
gauges.
Appreciate any help.

 

@Doug_Brg_Crk
I just have the APR and changed the DV no other mods
HP increased by about 30HP
Boost has gone from ~7 to ~19 psi
No real change in fuel consumption
Acceleration is incredible a real kick in the seat
About 80K on the car

 

Just did the APR Stage I upgrade on my 2003 225 with 72,000. Love it! Really like the switching method with the cruise control. Done by Achtuning in Redmond, WA.
You might think about a new diverted valve. I bought a new DV, then blew one on car within a week. Upstream O2 is out now, so I'll replace both.

 

Ended up going with unitronics 1+. Already had upgraded dv - kompact plumb back 25, but was having issue with variable boost with wot. Changed dv - went with forge 008, did not fix problem. Turns out n75 was problem. Replaced that performance is awesome. Also installed dd42 intake. Love it -amazing how you can hear diverter valve now. Performance increase is huge - and I actually get better gas mileage. Am under 10 litres/100 km

 

i had a stage 2 chip put in at audi on boundary absolutely awesome buy, such a significant difference
