the car was far from tweaked...i only took it out one time with the relocated battery, kmember, new tranny, 4.30 gears. Doing all that picked me up a tenth and a mph first time out over my previous best (done in a negative 500 da...follow up was postive da a little over 1k). New tranny had in issue i ended up fixing afterward by swapping to a different fluid, and well in the 12.4x videos you can see my cars suspensino had a lot more in it. You can see the front shocks were set way to loose. All said and done car has another .2 in it easily maybe a little more down the road.
