I whole heartedly agree, and he is the only vendor that adds the logic to hold gear in SST mode, that I know off. That alone makes his tunes amazing.
He has given me an extreme amount of guidance, compared to what would be expected, and is super knowledgeable. He also answers all of my questions, little or big, and gives factual evidence to support his answers.
And, well, the results of my Dyno run and track times speak for themselves. We picked up over a full second in the 1/4 mile on 93 octane, and since then with a few more mods and tune revisions (including switch to E20) my car makes more AWHP and much more AWTQ than stock at the flywheel.
