Hey guys quick question I just flashed a different tune I wrote onto my car last night and it barely runs / like complete shit with the maf plugged in. Unplug it and the car is an animal, I'm at work so I haven't been able to look it over again on tuner pro but does it sound like the maf scaling is off? I lm now wondering if I had forgotten to switch from hitatchi to Bosch on tuner pro, however I was under the impression the car wouldn't work at all if the scaling was off, any advice is appreciated!

Yeah that's the plan I just don't get out of work for a few hours and have been tossing ideas around all morning so figured I'd ask lol, thanks

No advantage to Hitachi except for anecdotal reliability stories. Ymmv
