Well, it's been exactly 12 years and 100,000 miles since my car was upgraded to Stage 3 + Toys.
She continues to be a hell of a lot of fun and has been extremely reliable, with no problems at all other than a fuel pump replace and a few clutches
Still shredding tyres in DAB3 with about 21PSI on 91 octane Union 76 Premium.
Thanks to all the PVO - SRT folks for making the Stage 3 kit.
Totally worth every cent of what I paid for it.
And the S3 coilovers (over 100K and no issues at all).
And the whole car (normal maintenance, oil Mobil 1 0W-40, Filter K&N HP2009, trans fluid every 6-8K with ATF+4, MPSC brakes (over 100K and still lots of meat).
Just finished a 1200-odd mile trip from SF Bay Area to LA and back up the coast highway and she ran perfectly averaging between 28MPG and 34 MPG on the freeway.
Planning another trip, this time to Yellowstone next summer, about 950 miles each way.
