I am having V2.5 loaded into my Australian Stg2 Golf R. What is the upgrade
in terms of TQ and HP and drivability due to this APR software update?
The email my dealer received from APR doesn't say anything about the improvements.
Rafal, You should contact Mullerhaus. They have it running on Jonathon's car and seem very happy with it. Other than that have a look at the thread on VWROC which has dyno on it.
From what I have seen and heard it's slightly more power but mainly improved power/torque in mid range. Addresses the previous issue with Turbo overspool.
I belive that power is roughly 400hp/400lbs but few mention they were 420/420 which would be very strong.
