AAM charged me $700 for Osiris, and $600 for a tune. Gah....
I can handle $300 for a re-tune from Hills.
AAM isn't an authorized Uprev tuning shop. That's why they made you buy the full tuner license and cable for $700... but $600 for an N/A tune JUST LABOR? HOLY MOTHER OF JESUS...
AAM is garbage. Always has been and always will be. Go to Hills if you want it done right. I don't have experience with JE, but it seems like they also know what they're doing.
Well OP asked for FI tuning shops in MARYLAND. Def go to Hills. I haven't heard any complaint about Hills Garage from anyone from this forum so far. That's always a good sign.
