I'm not understanding... How does that graph show that OBDII is detrimental?
Those are some nice gains in the midrange with the VAFC tuning, but isn't 4600rpm a little low? ~5200RPM is stock...
Also, JMCN, those are some NICE numbers for a bone-stock '97 SH
I will be doing some baseline runs on my bone-stock 2000 Base within the next 2 weeks hopefully... then I'll put all my mods on, and I'll do some more runs... Hee hee
