their website is suggesting gains of 8%HP and 6% TQ for the otherwise stock 35is (i.e. stage 1)

Seems like its more worth it for 35i.... 30%HP and 38% TQ stage 1 gains

No values in the Y axis but seems like 35i and 35is become pretty similar at "stage 1"
Seems that is how i read it too...8% and 6%, isnt bad but I was expecting quite a bit more, the stage 2 wont be usable for a stock 35is as no plans on a front mounted inter cooler. My question is why isnt there a spot between the stage 1 and 2 8/6 vs 31/21
