: Before we go onto the power aspects, let's look at the air fuel ratios.. (this is the giveaway)..

: Either this car hasn't adapted fully, or you're going to be seeing melted Aluminium quite soon.

: Take a look at the AFR readings..

: Running 14.3:1 at WOT at 6000+ rpms..

: (not for too long)

: Now, let's go to the purported "HP maximums"

: 281 vs. 273.4??

: Now I see the numbers.. but I certainly don't see an 7.6HP difference in the actual graph.. Oh, you mean the anomaly where you dropped off the throttle.. sorry folks.. that don't count.

: (Did I mention hidden agenda?!? ;)

: Now.. 275 vs 273.4 is more "realistic".. and if I have to give up 2 HP to keep the motor together under sustained hi-speed, then such is life.

: (But I dont..)

: Although I'm betting you'd find that in a few minutes, when the car adapts the midrange out, you'd see a big difference.

: PS: Oh, and the "my car blew away the other one" is completely BOGUS, as you won't even SEE the effects of 10hp in a drag race, it will be lost in the "driver differences"

: PPS: This is exactly why I tell people to find
: a dyno shop that can also EXPLAIN the results
: to you in a scientific manner. There are few
: around..
