I love my AccessPort thingy muh jiggy.
I bought it from Mazdamaniac mainly because of the Calibration Service. Will it make more power? yeah it will but there's better reasons to buy it:
- Increased OMP settings (more oil is a good thing)
- Fans kick on much sooner
- Leans out the AFR's. The stock mazda programming runs
very rich. I would hit 11.1 AFR as early as 3800 rpm with the old mazda tune.
Oh, and did I mention I picked up about 15 whp?
