#7 of 11 APR Upgrade to GTI by 2gtiguy

May 10, 2010 (8:25 pm)

Nectar (et al...), I just had APR's ECU upgrade done on my 2010 4-door GTI. Went from 200HP/207lbs to 254HP/296TQ. $599 for the software plus $100 for the install at the top-rated dealer in the area. Worth every penny, my friend. The one thing I felt was lacking (that's a strong word) in my GTI was the HP/torque relative to other cars in the class. The chip flash has more than taken care of that, and at no cost to my mileage (unless I stomp on it a lot, which I sometimes do.... ). Anyway, I'm with you on German cars, and I love my GTI.

Two questions on your chip upgrade.
  1. Does this affect the warranty? I believe it does, but probably only for engine related problems.
  2, Where did you have this done?
 
 My fun car is a 2006 BMW Z4 M Roadster (330 HP) purchased new. I put this car away in the western Massachusetts winters, I'm looking for a four season fun car and the 2010 GTI is at the top of my list.

If they can detect the chip and if the warranty claim has anything to do with the powertrain, you bet VW will deny it. There's nothing to say that the car's transaxle is going to enjoy the extra torque as much as the driver

Solid points. I don't drive it like a maniac, so it hopefully won't put too much strain on the transaxle. That said, APR's Stage I upgrade is designed to work within the specs of VW's existing equipment (which, being German, is outstanding), so I don't think it's an issue. Also, APR's upgrade includes the ability to switch back to stock settings AND lock it out once you've done that, making the upgrade "undetectable" (I used quotes because I haven't proven this yet). We'll see.

Well the only way a chip is going to get that kind of power is cranking up your turbo boost, and so they are probably going to be able to detect that. It would be interesting to dyno the car to see what the actual HP ratings are. Also might be good to know how much boost they are dialing in--hopefully not excessive.
 
I'm modifying the supercharger on my MINI and I'm taking precautions for the added boost with cooler spark plugs and larger intercooler intake. One always has to be concerned with heat build-up when cranking on the boost I think.
