maybe i got lucky but the street/ highway manners of this tq is way better than the holley 750 dp, holley 670 street avenger and the 750 demon without touching a thing. although weather has been bad so i haven't been in hot weather or on a long trip yet and i haven't been to the track for comparison but the seat of the pants says better bottom end for sure and mid to top seems great.
 thanks for the links bullitt. ive been trying to find a single plane for a tq but not having any luck. i think i will be doing a 408 this winter and i believe they react to single planes better.

From what I've heard tuning a T/Q to performance motors can be difficult, they rely very much on vacuum signal.   Local guy had to experiment with the metering rod spring finding a weaker spring was necessary on his 440 with longer duration cam. Even too low of an air box can change the way they respond.
