the denser air will make you run lean? serisouly?
good thing the amount of fuel injected is determined by the map sensor and a thermometer... seriously, im not bullshitting you
The subaru guys had a problem running lean. I guess it all depends on how much gas your injectors can squirt out. They have to max out there duty cycle at some point. Especially with a procede ontop of that. But I have no idea if you can max out direct injection or not. But running lean is and should be one of your number one concerns no matter what type of ecu or piggy back you have. Lean is no laughing matter.
