[todas**t]

dude everybody knows when tuning a car, that u focus on the b4 dyno run , and after dyno run - how much power increased, the shape of the curve, and AF ratio. A lot of differnt dyno's will read different power figures.

If his car was tuned on a higher reading dyno, and gained 10kw, and then later went on a different dyno and the peak rating was lower. he Still gained 10kw ...period. You cannot compare differnt dyno readings with each other. only as a general figure, as some will read more accurately than others, the Temperature may be diff etc.

if u put a stock car on, and a moded car on then u will know the difference and that was done......on the same day, stock car pulled 100 i mean dead stock and a moded car pulled 105 that with header exhurst cams and ecu, would u be cut after spending that much and gain a lil....
