by using this clamp i bought for SS, he then the portable lm-1 wideband for live data of OČ levels..
ther only acceptible dyno tune for me would be done on the mustang series dyno, which actually applies a load and facotrs in the weight of the vechicle, wheels size, etc (simulating real world resistance and road friction). an awd mustang dyno would cost a mint, however......)
ese
ps- i still believe the road tune needs to follow, just to add a margin of safety for any unforseen spikes or lean-outs...
