We dyno'd and tuned my friends fathers Stillen SC 350 yesterday. We started with a baseline (supposedly previously tuned, coulda fooled me) of 270 rwhp going rich from about 4k on up. After a bit of adjustment with the SAFC II we got it to 311 rwhp with a nice safe 11.4:1 across the board. We've done about a dozen Vortech VQ's here at our shop and they have all done from 330-350 rwhp, so the Vortech definitly has a top end advantage on the Stillen. Haven't dynod an ATI car to compare to yet. Just thought I would post this up lest anybody was curious.
