D's 04 STi tune review, Stage 1 for CA gas grade.

I have had my 04 STi since June. I had a Talon before that, and the STi felt like a rocket in comparisson. Once my tactrix got here I did some logging, and found that my peak boost was only hitting 9.5. Bren worked with me and told me to check the T setting for modifications as this is a common symptom.  So much for rocket. I fixed that by putting the restrictor pill back where it belonged(previous owner had it in the wrong arm of the "T"). Logs showed boost was up to 13.9, and the car really felt stronger. I drove with that for a week and then flashed Brendan's stage 1 tune. What an amazing difference. The engine is smoother across the entire RPM range even at idle, spool up arrives 300 to 400 RPM sooner, low end torque and mid throttle response are fantastic. The car pulls like a demon from 2800 to 7000 RPM now with no noticeable drop off in power delivery. Despite my much heavier foot in the last few days, my mileage has actually improved since I flashed the stage 1 tune. Logging with the stage 1 flash installed is pristine with no areas of concern at all. I am very impressed with the results, both at irresponsible speeds and driving easily around town.  I would recommend Brendan's services without any hesitation to anyone who was interested.
