Oh yeah thats as easy as telling the computer to not throw a code for that anymore.

So can it still go off the maf, but just not report the code?

That's a good question, I'm fairly certain that you can yes, it will just not recognize any faults in the system so you won't know if the MAF is causing issue.

You would have him set it to "No MIL reported"

Once I get my bb tune I'll request they do that for me. Thx Dan.

I thought it’s been running better. I’m not sure when it started doing it because I’ve been concentrating on the trans so much. When I found that broken vacuum line in my supercharger bypass I was wondering where it plumbed into because my misfires were happening in the middle cylinders. I was seeing 20-40 per cylinder in a 100-cycle count. I’m not sure if that vacuum hose fixed it or if it was something else I did but I’m getting zero misfires now. It was starting to throw P0300 random misfires pretty regularly. I know that hose should account for a MAF code and not so much a misfire code but maybe that hose plumbs into an intake runner? I’m not sure but I’m happy.

Amazing! No misfires. I don't even know what that would be like.

It’s been a year and a half (or more) that it’s been misfiring, I thought it was the intake gasket on the blower and I put off pulling it because it’s a bear to R&R. I think that had a small leak and kept getting worse until it completely came apart and I noticed it. It’s back by the firewall and hard to see. The truck has never run better. I’m really happy right now. I went from stressing thinking about the worst case scenarios with the trans and the bad misfires to now, where everything is as good as I could hope for. Amazing.

Go look for that WRX again!

It was already running good at that point, probably why I was able to give him a run.
