Sudden power loss

Yutnaka

The tech said that my cel came from the test pipe. I am wondering if a mechanical cel fix would work to prevent this even without a tune. Any thoughts?

yes, call them on the phone and ask for the code you were getting.

You're dealing with a high-strung engine that doesn't take well to mods. Just about any mod that will give a decent increase in power will confuse the ECM and trip a CEL.

Baer383 is right - if you are going to mod, you need tuning software to support your efforts. The ECM will only self-adjust so far before it thinks something is wrong. With tuning software, you can change ECM setpoints and coefficients to values that match your mods. It will also be a tremendous help when it comes to troubleshooting.
Most of the tuning software packages offer the ability to turn off some functions that trigger a CEL.
