I'm no tuning expert but here's my two cents why cartek tuned it that way:

Cartek makes more power with less tuning. their ported heads are efficient and don't need a lot of timing. even with my current car, i was there when he tuned it, and each pull he lowered the timing and the car was making more and more power. its just what they do, so nuttin wrong with it
i couldn't believe it either.

They know i road raced the car, so they set it up very conservatively with anticipated 30 minute sessions on the track. thats a lot of abuse and a lot of heat generated, so he took the safe route. I can't complain about being too cautious when it comes to that type of stuff.

they tune so that O2's are not read when car has mild to big cam. That is how they do it so the tune doeson't "learn out". Many tuners do this as well.

Considering the mild setup (small cam and older design heads), the HP #'s are stout and the drag strip performance is right on, considering the road race setup and full weight of the car, and only 1 day's practice with that setup (before the DS broke at the weld and ended the day early). There was probably an 11.3 in it and that is with ET streets; ET drags would have been better. 8)
I have no doubt that you can coax more power out of it with HP tuners, you are good at it and its a better tuning program than ls1edit.
