Hi FS Turbo
Could you please check for me that the megatune has picked up the correct ini file for the map sensor on your V2.2 board .
when i first had hassles like this it was calculating the wrong map values.
Check "Set" Code variant ,"set" speed density ,"set" mpx 4250 is all good ! and if so i would dump the lot start fresh reburn the image on the eeprom and get a fresh mt ! You may a corrupt setup .
good luck.

as in more air to same fuel... 14.7:1 means 14.7liters of air for 1 liter of fuel, ratio. So more air in there would mean leaner. You've got the rich/lean backwards

Except its ratio by mass, not volume.

Hi FS Turbo
You talk about low impedence injectors ,(Have you got the PWM in your constants sorted ?)
Or maybe a injector resistor pack wired in be more reliable atm ?
I started with lows and made my own volt drop pack out of a group
of 10watt resistors .I could give you a picture and their values of my
success if you wish?
You could be over doing your injectors ,and its giving you wide open
none adjustable results.
Cheers
