Would you also maybe describe the problem as a "stumble?" The was a similar problem on an El Camino at Best of Show with a supercharged 402 from Turnkey, but it has since been resolved after a trip to Westech. Actually, the last three or so cars to go through BOS, including my own, all had a similar issue where the car had low rpm tuning issues. If you can find someone to work with the system it is probably a simple fix.

You could also tear out the computer if there is no one near you that can tune it...

I would describe it as a rev limiter. I sent the ECM to turnkey. They claimed it had a permanent 2000 rpm limiter in it,apparently back then they didn't have a time lock break in,they expected you to bring the car back to them and they could look the engine over and then remove the lock. So I was told the lock was removed but the car does the exact same thing. So my suspicion is the lock was never removed. I'm debating if I should try sending it back to them. I will contact westech to see what is their take on it.

So i sent the ecm back to turnkey and they confirmed the rpm lock was removed. So i bought a codemate and ran a scan, im getting a code 41 and a code 81. Is there anything obvious i should check for or start to look at? All cylinders do fire as each primary gets hot as soon as the cars started.

"The code, 81 I am suspecting a cam/crank sensor issue or possibly injector driver problem. The code 41 correlates to the cam/crank issue, which would indicate a bad coil or misfire. A little further investigation on exhaust temps. will tell us more. This is a very strange problem"

Do it right and toss that system and get someone to tune the FAST XFI or similar... You've heard from the best/brightest on here... and for the most part they've suggested you get a more tuner friendly system given that you don't have the USB dongle and cable etc... and you don't have the WB O2 sensors...

Or -- ship the car to Mike -- it's not that expensive compared to the cost of rebuilding your motor...

Just saying -- after reading the thread from the beginning -- you're not getting anywhere going about it the way you are. Summer is coming....

It's an OEM system with an engineering pedigree that the aftermarket systems can't match. Unfortunately, because it's an OEM system it's mostly locked up, with little aftermarket tuning software support. That's a shame, because with some good software, these systems would be a great value. At this point, without a dongle, cable, and no progress in months, I agree it might be time to throw in the towel and go with a friendlier system.

Edit: if you do decide to throw it away, let me know.

Yeah -- It really isn't like me to just butt in to someone's thread and say something like that... but after seeing the dates -- and reading the questions and responses... that's the conclusion I came to. Dude... just spend a few more bucks and get 'er done.

Hey! This may be the first time you and I have AGREED!! A new beginning! <olive branch extended> HAHAHAHAHAHAHA
