Hey...so basically when I give a decent amount of throttle the CEL comes on (although it doesn't read an error code) and I lose power completely for about 2 seconds and then the light goes off and it's fine again. It's a 00 civic si with low boost. I'll upload a datalog I took. It's at 1:18 when it occurrs.

Let me know if there's any other info you need. I'm a bit of a noob when it comes to tuning.

Do u have a wideband

Unfortunately, I do not. Any ideas?

It is a boost cut.

Okay. Were you able to look at the cal? Is it something simple that I can change in order to correct it? Thanks for any help, I really appreciate it.

Did your tuner tune this for you?

He did, and it was close to a year ago. If there's something that looks incorrect on the cal it could be that I corrupted the file by updating to a new version of Smanager...and I saved over the original file. I emailed my tuner to see if he can send me a copy of the original file hoping that will fix the problem. What do you think?

Any suggestions?

You need to either get the original tuned file from the tuner, or you will have to start with a new calibration and get it retuned.

change your sparkplugs gap them to .25 and get 8's
