Thanks to the guys at Streamline Industries in Salt Lake City, I got my R flashed with the GIAC software today...and I love it.
I had been following the threads and the numerous positive comments about APR. However, the group at Streamline is really the closest, most friendly, professional and knowledgable one to me here in Utah. As many forum users have stated before, go with the tuner that is trustworthy and will take care of your car. These guys really did for me.
Living in Utah, we are limited to 91 octane fuel. I really wanted a tune developed for that gasoline rating. I talked with Austin at GIAC in CA at the beginning of the week and he was very upfront, friendly and straight out tech savvy. He said that they had finished the development of the software, but were waiting on some final dyno numbers before marketing the tune. I told him that I was interested and he sent the file to the guys here in SLC to flash my car. They did it this morning and then ran a bunch of data logs to confirm the way the flash should run, especially given that were are at significant altitude and the development was at sea level. GIAC feedback was that it performed flawlessly. We did not dyno it, but the car's behavior transformed enormously.
I can say that the throttle response is super linear. No hickups, no drops, no drop off. Torque is noticeably stronger at any rpm, even in the very low range around 1500-2200. Once the engine hits 2700 rpm, the turbo spools immediately and everything just takes off. Like night and day compared to before.
Talking with the group here and the guys at GIAC, the restrictions to power now are the airflow in and out. That means that a CAI and downpipe are in the immediate works. Still doing my homework on which way to go. The good news is that I won't need a reflash to accomodate the downpipe or CAI. The software tune is adaptive for these. Next thing coming down the pipe, I understand, is a reworking of the software for a high-performance fuel pump...will have to wait and see.
Oh, the great news about the GIAC tune is that it comes with three switchable programs, stock, pump (91 octane) and race/track. These are switchable via OBD II mapping cable that comes with the software install and will be made switchable via bluetooth/iphone app I hear.
Anyway, love the car now. It has been said before, this is how it should have come from the factory. So happy I went with a shop that knows what they are doing, they made a new customer for life. Also ecstatic to have a tune developed for our fuel measure.
Now, on to the intake and downpipe. Any suggestions are welcome.
