No J,, it actually did it after the header install.

Oh well that makes sense. I took a video of my AFR readings so you guys can see how all over the place they read. Don't rag on my gauge install, still have some tidying up to do. Want to paint the plastic behind them black in order to blend them in better with stock gauge cluster bezel. On a good note (knock on wood) I have not seen a CEL sense I removed breather on the 5th. I will post link to vid in next post. Stand by...

Ok here is the video. Tell me what you think is going on with these readings. As you can tell this is just under light load cruising. Sorry for the shakiness. It's hard to keep steady with my new Pfadt suspension

Hard to tell ... 17 to 19 if you are at all on the gas is lean .. 14 to 15 on idle or light load is where it should be ... It will go to 19 when you let of the gas completely, then should drop again. 10 is rich. I would visit a tuner ... Your gauges could be off .. Or a better tune is in order

J, I think possibly your gauges are off, the boost is way off too. We both have the SLP TVS 2300 Maggie and my gauges read no where what yours read. I really think you need to pay a visit to a good tuner and scrap the SLP tune in a box. The SCT handheld holds 5 tunes, if something happens where you need to bring it in for warranty work you can always load the SLP tune back on. But you need the services of a good tuner & dyno IMO.

Well I never went into boost in the video. Are saying my vacuum readings are off?

I know you didn't hit boost, but yes looks like the vacuum readings are off.

What is the highest your vacuum readings go?

Im just spit balling here but do you think that if the weld job for the bung has any kind of unsealed/unwelded areas it could be bringing fresh air in causing these crazy readings under light load?

The only time to look at air fuel guage is when your wot ... It should stand straight around 11.5. The guage will make you crash, it bounces all over the place because your off the gas on light load. On the gas it should drop ... Off the gas it goes up. I would see a tuner, he an check the guage vs a dyno, if its your tune it will be money well spent.
