I run NO o2 senors. car runs as good as stock

Then you have a 24/7 CEL.

You still shouldnt have a CEL if you are using a antifouler. If your not using one go to autozone and get one and you CEL from the exhaust will be gone.

We get a 24/7 CEL even with the 02 sensors plugged in. Car actually runs better when there IS a cel....

Reseting the ECU and getting rid of it, the car feels sluggish. Then when the cel kicks back on...it's alive again!

The CEL on our car when you read the code, comes back as the PRIMARY O2 Sensor, not the Secondary. Anti-fouler trick does not work for us, and most people with the ZPI S-pipe, because the bung is actually pushed back, therefore eliminating the CEL. So, the Anti-fouler trick is not needed with this S-pipe.

Well, if you make a trip to the track, most " quick / fast " cars have a CEL. Dosnt bother me. Its just a little light bulb

post up when you find out whats up.

i notice this "bogging" to be more prominent when the car is hot lapped. when i give the car a run after letting it idle for a while, it seems to hold the tune. however, once i do a run right after that, i get that same bogging at around 4500 rpm (doing second gear runs).

one thing me and my tuner have noticed about emanage and the tc is, the tc is smarter then the emanage. the tc will eventually outlearn your tune and has been good practice for me to reset my ecu about every 3 weeks. remove your efi fuse and wait, reinstall then start your car and idle it for about 10 minutes. this allows the emanage to take control again. some people argue with this but i can speak from experience in my vehicle, it helps.
