I've been fortunate to spend time driving with Steve in the passenger seat with his emulator, LM-1 and laptop as well as with him next to me on the chassis dyno for both engine tuning and product testing.
3.2L before with SW chip, Dansk pre-muffler and Dansk final muffler and 3.5L after with many mods and Steve's optimized chip. Notice the "flat line" a/f ratio in red?
On the dyno, Steve coaxed 7 whp and 10 ft/lbs from our initial 3.5L run of 239 whp and 214 torque. Search in the archives and you can read all about it.
I am in a fortunate position that dyno time costs me next to nothing.
