Thanks for your interest and replies.
The tuner uses Uprev and car was previously tuned by them when NA. He said there was still more to be gained, but he did not use the stock Uprev tune that you can get with the Stillen kit.
I already have a Cusco 1.5RS LSD with 4.08 gears, so it does really take off.
These are the NA results with various bolt ons and tuned.
