They are anti obd1 lt1, like everyone else. There is somewhere else we could go, but time is of the essence. I'll baby it and watch the afr, if it looks like shit, it won't get dynoed or it will be limited in rpm.

That's to bad. Do they do obd2?

I gotta call them again, but I doubt we are gonna have time. We may run it just on motor for break in. No idea yet.

Tune shouldn't be that far off though. It was very safe before. Honestly, I think the pcv/catch can setup had issues, and that's why we had what happened happen, that and along with everyone saying it's dead etc etc because no one has faith in stock bottom ends led us to this. That motor was fine, it was a blowby issue that wasn't really an issue. Shouldn't have ran an open breather, especially with a maf sensor. Live and learn though. Should be a whole Lotta mean soon.

Really? Why not? I run an open breather.

It's a vacuum leak. It allows unmetered air into the engine after the maf. I researched it extensively, and spoke to more than one person on here about it. It can cause split blm issues.

Wonder why i have none of those issues

Taken from another forum :" it allows unmetered air to be sucked in the open breather and then it bypasses the MAF and goes into the intake via the PCV valve on the back of the intake manifold. If you want to run an open breather, you need to plug the port on the intake where the PCV connects to."

Albeit it's a small amount of air, but it does do it. I put it back before we pulled the motor apart and the blm's at idle were alot better.
