I had a 4094 installed recently, and since then I have received the message. Itll randomly do it driving easy or hard, no codes..fuel filter was just changed maybe 200miles before install 80%, it was not doing it before installing the turbo. Obviously I had to have the tunes adjusted with the turbo,it does it on any tune, Truck is deleted. Autocal said MAF 40. I do not have lift pump, I have not noticed any problems with the transmission other than neutral hanging on first start when its below 20 and wasn't parked in the garage. It had not previously done it ever. It's annoying buying a turbo to get me anywhere faster and I have this pop up lol. I have searched, most people suggest maf/air filter/ fuel filter/disconnect batteries no luck. Any advice would be great. Thanks
Engine power reduced, no codes help.

Yep, under boost code. Call Mark at Danville Performance, this I a known issue. Some LMM's do it some don't...
I had a similar problem on an LMM I tuned last year, ended up being the MAF scaling. Get your tuner a log file and have them increase P101 error time a bit. Certain LMM's are very picky with this reading.
