Throttle response it very touchy--- the off idle is a neck snapper--- Wife did a bit burnout without really trying (and she doesn't drive that way)--- No turtle as of yet, I bought the software/jigs from Jeff Arnold, and will be offering them soon--- and some different turtle options (I gotta play with it a bit).
The carb is oem-- 100% 73 and never touched... In general driving, it's fine, normally in a 5000# car you don't nail it off idle-- With a heavy foot being careful not to stop too hard it'll make the transition nicely-- and there goes your gas mileage!
The wagon puts down 190 rwhp @ 3800 rpm, 300 ft. lbs at 3600 rpm--- nothing but torque.
