So the instructions are incorrect, we linked it accidentally to our Mazdaspeed 3" intake. I passed the info along yesterday when I noticed it but it hasn't been corrected yet I guess.
As for the dyno, the key is the difference in the numbers, not the actual numbers. Our dyno for some reason reads very low, but is very accurate at the difference. When I put my Mazdaspeed 3 on the Dyno (265 factory) it told me I was doing 220 with a Stage II intake and Accessport..... clearly it reads low. Same day my co-worker ran his RX8 on it... and it came up with 160hp...... what??
The fact of the matter is a dyno is a great tool for showing improvement over a previous reading, but ever dyno will read power different and it's an arbitrary number.
