This beautiful 05 STI (White/Gold) showed up for a dyno tune as a referral of a great old friend and tuner himself. Excited as we have heard all the DOM3 buzz and wanted to see what it was all about.
This turbo reminds us of the HTA Green 8cm that we love so much. Spool was nearly identical as was the top end curve on the dyno. The 2.5XTR never could reach these power levels at the same boost which is why I always recommended the HTA Green. We stopped this tune at ~420 due to the stock rods and overall longevity. It had more in it with an aggressive tune for sure.
Don't forget to take advantage of our $50 off ALL STi February. It's the last week!
