So I'm curious how other peoples approach is to tuning with Meth Injection. Cause when you start spraying meth the AFR goes rich and your AFR error is thrown off and can't really line out your fuel trim cause its now richer from the added meth.
Do some tune it without meth and turn meth on after the AFR is lined out. Or a different approach. I could see this way working on low boost with meth added for more safety. But on high boost apps doesn't really sound like a good idea to tune without it and add meth afterwards. Looking for some insight on future tunes since all the local guys I've been tuning are now starting to get into boosted setups.
