theres a difference between conservative and below 10:1 rich. i did a FWD SR swap for a kid and used the JWT computer and i had to take out 18% fuel on his SAFC just so it would idle bc of how rich it ran. ive been turned off by JWT, esp when we have something so much better locally. im sure if i lived in the same county as JWT, tuning would be a different story, but my money woudl rather go to scott, than across the country.
