I looked at the 10-day last week and took a gamble. I made an appointment with SGS for today. It couldn't have worked out better.
The 1st graph below is from Hybrid last year. The car had cai, 75mm t/b, upper plenum, o/r pro-chamber and flows and Modular Depot mail-order tune.
The second graph is from today. Car has everything above plus cams, longtubes, u/d pulleys and SGS custom tune.
EDIT: both were not corrected in the same manner. So, I'll remove the fluffy comparison.
Dave @ SGS actually didn't pick up much power over the Modular Depot tune, but he made it a little more driveable in the lower RPMs. He actually likes a leaner A/F and lower timing. He thinks that's safer than more timing with more fuel.
Enjoy:
