my experience with Scott Siegal's tuning
It's soooo stock?

A dyno tune should always be followed by a street tune to assure performance in the real world.
This is why my and every other "dyno" tuned only car I have seen locally never produces the same boost # on a 1-2-3-4-5 gear pull as it did with a straight 5th gear pull on the dyno. Rally cars are all "street tuned"

same thing with wideband on the dyno is done on the street. wideband right in the muffler, then from there it connects to the laptop.

by using this clamp i bought for SS, he then the portable lm-1 wideband for live data of O² 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...

Since I have a dual tip muffler. We had to use the unused o2 bung (on the top of the DP) to hook up the wideband.
