@@hypnotico7051 If you only look at max vs max. stock hp at the crank is 350, they say max with a stage 1 93 tune is 431 which 80 horsepower is correct but they claim an increase of 139 at 4100 RPM which is not where peak power is made but if you compare dyno graphs stock vs stage 1 93 @ 4100rpm, the tuned car is making 139 more horsepower (at THAT rpm). who knows if it's true or not but I can see it being real with their tune making the boost come on harder and earlier.
