Thats sounds right. And you had a great 60ft by the way. Was that on street tires?
For just over $1000, you'll do a lot better: Get a chip from
www.customchip.com ($300), a 80mm MAF from a Lightning (have to get that when you get the chip, $100 or less,) some 3:73's (~$400 installed,) and an H or X-pipe ($150-450) and you'll be able to start kicking some *** .
