I did send it back for a re-stall. I just think it could 60ft better. It is a 15:1 565 in a 2200lbs Corvette, with me in it. It was around 1.22 in 60ft. It had 4:30 gears and the T/S super 8 5800 stall. Whatever I do I am just looking for educated decisions. This is my first spragless and I am wondering if the 8 inch regular converter would be faster is all. I would hate to be giving up 2-3 tenths!
