hi guys! Lurker here for the past 5 years, tuned my old TIP allroad very successfully, and just picked up a 1.8t avant to mess with. having trouble with getting the actual pressure and specified pressure MAP close to what they should be. ev14 1000cc injectors, HPX maf in a 2.5 housing before the TB that was scaled pretty close to properly(stft at idle warmed up are great),stock map sensor. but every time I do so much as take the BONE stock file, and JUST touch krkte to scale correctly for my injectors, correct the checksum and flash, it says my actual MAP pressure key on, engine on/off is over 1400mb?! no matter what I do I can't figure out why it does that. a stock file flashed will read the correct 1010/1010mb, but doing anything with KRKTE makes the actual reading way off? voltage from the map stays the same, tried 5 different sensors, 2 being an OEM large style. that is the only thing that is keeping me from being able to do anything other than part throttle/ idle tuning. It also displays a very high G/S at idle and load will cap fairly quickly part throttle, I'm guessing I need to lower maf scaling and increase KRKTE to get fueling more correct which would lower load but the MAP reading is the only thing that is keeping me from doing that. any help is much appreciated, Thanks!

Sorry about that, forgot to attach one of the files. this it literally a stock CH box file with KRKTE touched, and MAP actual reads 1400MB.
