Ive learned that our cars make more HP and tq then seen on the dyno. I know this has been said but our knock sensors pull back alot of time and with headers, a axelback, etc all create more vibrations that our hypersensitve sensors pick up. I have done a couple different dynos... one says 250, one 255, one even 281, and another even higher at a cold start after leaving off for over 24 hours to say about 291. Now I look at my 1/4 mile times and i see that how can a 250 hp car, if dyno was so correct, can run a 13.8. its timing thats pulled and of course heat soak may effect it significantly too.

now if im wrong at anything correct me. Also the vararam sucks on the dyno. Not sure why but they do, on the track is a different story. On the same day i gained .4 on the 1/4 mile with just a vararam added. It works.
