Are you referring to the first photo?  That’s not timing pull, that’s fueling adaptation.  It’s removing fuel; running slightly rich but well within the ECU’s ability to manage.

Pretty sure he's referring to the -6+ degrees of timing pull in the log he attached. I'm guessing Mirza tuned.

You're going to throw positive deviation eventually with that weird boost request and wgdc lockdown.

Doh!  For some reason didn’t see that there was an attachment.  Mekes loads more sense.

Seems like you need less timing or more octane/meth!

Meth injector is 2'' after the MAP sensor, and its before IAT.

Any recommandation on injector setup ? maybe dual injector ?

I’d put the meth injector right before tb also check the pressures. The amount of timing is pretty spot on for a meth issue

I ordered multi-input controller to set meth inject from IDC,  I will put meth injecteur just before TB. also I have a new mix, 50/50 by weight distilled water/methyl hydrate. I don't like injecting windsheild washer fluid, its blue -40 but I think it contain soap, I will testing soon thank you !
