Just learning how to tune and may not have all the info required, but this is more a general question. I'm getting P1514 every time i try to tune Speed Density. Starts out fine as long as I keep driving at 30MPH and below with no load on engine. As soon as I start to increase load, It goes into limp mode and throws P1514 code for TPS. My question is do I need to change a parameter in calculated airmass? I did as much research as I could find but most were posts from 2007 era which may be old and obsolete data. And didn't really give me much insight as to what i should change. Not to mention most were boosted setups.
