As mentioned most tunes available are all similar, comes down to your preference.
My experience with GIAC 98 tune with CAI:
- Removed flat spot in 3500rpm range.
- Torque range from stand still is phenomenal
- Improved fuel economy (480-550 per tank).
- Most importantly a few more HP's. Nothing dramatic, but enough to put a smile on your face.
- High idling upon starting up the car (usually in the morning or haven’t used the car for a few days).
If UM (United Motorsport) tunes were available here, I would switch as I heard VG reviews on the vortex forums....
Justin "dainese" has an APR tune on his .:R, which is very nice when I drove it, but GIAC is a bit more aggressive = fun.
My 5 cents :cookie:
