Post FBO Stage 2 Issues
Hey all,
Having an issue with vibration/hesitation on throttle under load ONLY between 1500-2k RPM. Car vibrates and shakes seemingly at the downpipe. Parts all installed at same time and first day had no issues, popped up on second day. Tuned with Bootmod3 OTS Stage 2 93 octane. Prior to this install I had no issues on stock with Stage 1. I have reverted tune to Stage 1 and Stock to test but the issue still persists (though it isn't as loud). Checked the clamps at downpipe and visually everything seemed good. Haven't had a chance to get it up on the lift yet and check everything else. Going to try reinstall the downpipe this weekend but hoping for some insight. Car runs great otherwise. Not sure how to attach a video so I uploaded to Imgur. View post on imgur.com Parts installed: VRSF Competition FMIC Active Autowerke Charge Pipe VRSF Catless Downpipe |

Does it happen around 2k rpm under light load going around 60mph in a high gear? There are a few of us having this type of problem we call a power stutter/hiccup that might be related.
