Total loss of power when accelerating

[tsapp1]

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

[tsapp1]

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?

[tsapp1]

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?

[tsapp1]

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
