My car turned 290hp on a chassis Dyno and ran an 11.78 @ 118 at the track .. Like you I was all worried about the dyno numbers . Then I said to myself I'm running high 11s something is wrong here but it isn't my car.
Bingo!! Thats why i'll NEVER waiste my $$ on that crap, yeah i said crap lol, all i care about are "time slips", for the most part, they don't lie, i could give a rats azz what HP i have, if it runs the way i feel it should run, who cares, i ran high 10s in my Duster, i couldn't count the # of people who have ask me, how much HP you running, i'd say...."don't know, don't care" lol.
