Looks like muffler causing all the problems. Car is now making 241 at wheels and over 200ft pounds torque.

Good find.

Just curious, how did you figure this out?

The reason that I ask is that I had a 1973 911 CIS engine that would not rev also. Found out that a mouse had stuffed a couple of pounds of dog food in the muffler when the engine was out to rebuild the CIS. Got the engine to back fire and it shot a wad of dog food out the tailpipe!

Pulled off the muffler and dug out the dog food.

Weird but another data point.

Actually we were stuck. Tuner said he thinks my muffler is junk so we decided to pull it and run it un muffled. Steve Rensport and Edelweis said something about restrictive exhaust systems and I just figured try it without muffler. My bling bling stainless steel muffler is junk. Anyone just run straight pipes off one of these motors? Should know today final numbers. Tuner says his dyno reads very conservative. This car was a stalled project. The early dyno sheets are from last year and that tuner wouldn't give me the dyno sheets with rpms or the right AFR sheets. Even pulled engine and re timed the cams.

The guy tuning my car at first place is a really good tuner and comes highly regarded in our area. Problem is he doesn't tune Electromotive systems or does he work on old 911's. I brought him a car that needed a few things sorted before it could be run on the dyno. It also had a plugged exhaust system. He couldn't perform with my set up. If I ever build another engine I'm gonna pick a engine management system that someone knows inside and out first. Ended up trailering my car from Philly to DC to get tuned and I'm paying twice for tuning. That's my fault for not doing my homework.

I've had problems with my electromotive TPS sensor also. When cracking the throttle from idle/closed position, I've had the voltage go down, not up as it should. Gives quite the wrong message to the ECU. Some fiddling around and repositioning and recalibrating solves this once you catch on. Irritating, though, and I don't know how it could get that way, as it is just a rotary pot.

For race engines, the Electromotive is really quite an easy system to deal with, as you don't need most of the bells and whistles. Can't see it being trickier for a street application, where you want idle stabilization, and part throttle optimization, than other systems.

You can teach yourself to be your own tuner - it is not like you are reprogramming a chip, just changing values in tables, which you can do at the chassis dyno with your laptop, and then see how they work. And you can check them again on the street, even change settings from the passenger seat driving around.
