It likely needs a tune if you don't already have one.

Oh Jeez, that's not good. I don't know enough about tuning to give any opinions. Do you have a way to read your injector duty cycle? I wouldn't think you'd be maxed on running 93 and NA.

Yeah, sent logs to my tuner, he had me do an ecu reset and do logs again. Said it ran fine after... apparently it’s trying to correct for something and slowly pulling fuel over time? It’s only been like 2 months...

He told me to run a pcv delete for a bit and send him a few logs to monitor over some time and see what it does.

You would think the tune would have fixed it

I'm having a hard time figuring out how the PCV system would affect the AFR. Deleted or not, my car has worked fine either way.

Are the adjustments included in the initial tune price? i.e. $800 for tune and refinements for one year or something similar?

These are the types of issues that worry me when it come to remote tunes and matching up on the street or on another shops dyno.

Then again, I have no experience with tuning.

I think that depends on the tuner. Mine was awesome. If there was something he didn't like or something I didn't like, he went back and fixed it.

Ditto. I had a delete/catch cans but was sick and tired of the ***-gas smell in the bay so I put the nipples back on.

All I know is Moncef from Admin Tuning knows a hell of a lot more than I do about this stuff.

But I cleared and reset the ecu, nothing else, and he said it’s on point again, and the car is apparently making small adjustment after small adjustment to the fuel and eventually (after 6-8 weeks) getting way too lean. But once the cache is cleared and it’s running strictly off his tune again, it’s fine.

So we’ve got to figure out why. The pcv is where he wants to start... I know that blow by can lower your octane levels and make the car do some weird stuff. So maybe it has something to do with that.

As far as touch ups and helping afterwards, he hasn’t charged me a dime. But has always responded same day, and told me to send him logs whenever and he’ll always look at them.

With my previous tuner, everything was covered up to a year, then you had to pay for a retune.

Anyway, gonna try a delete and see what that does.

somebody has an AN adapter for the breather side now as well. Might be Royal Performance but not sure. I saw it on book of faces a few weeks ago so there is a 0% chance of ever finding that post again.

I give them the specs to what I want the car align to. And I stand right at the bay door talking to the guy the whole time. Waving a twenty dollar bill at him.
