Just to give you a bit more info, I did a TPS sync test this weekend. Also, voltages are equivalent between the two sensors. The one thing I didn't do is measure the deflection of the throttle valves to verify. I've included screen shots of what they looked like at a steady state cruise. From a layman's eyes, it just seems like the SB engine is lazy. When throttles are sync'd (versus adjusting throttles to sync RPMs), the numbers between the two engines seem pretty similar. The exception to that is the RPMs and temperature. Notice the almost 6 degrees C difference? Is that enough to have this affect? The thermostat was changed in the SB engine. Is it possible a 160 degree stat was installed instead of a 170 (assuming that is an option)? I wouldn't be concerned about a 200 RPM difference at WOT but it seems notable that there is a 200 RPM difference at cruise RPM.
I am hoping to find the time to at least pull the plugs and look at them. I would like to do a compression test too but I'm not sure I'll have a helper.
Thanks.
