![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
i have a 04 gto and i just got done installing some stock 243 heads and a tr224 cam, i already have headers, we (me and my tuner) are using efilive to tune it.
i have a question about high rpm (4000-6000) rpm, it is acting like it is backfiring at hard throttle, but when we look at the logs, we cant see any knock or anything.![Icon Confused](https://ls1tech.com/forums/images/smilies2/icon_confused.gif)
also, anyone have similar mods and have a efilive tune that i can look at? thanks!
