Modular Depot is located right behind the Florence Mall. Be careful if you go to them. Make sure you know what you are talking about. I sent them an email about getting a tune for a JLT CAI and they said they could do it. The sales rep wanted me to book some time on the dyno for $500.00+ so he could write a custom tune. From reading some of the threads here, I don't think a custom tune for a CAI is absolutely necessary. I would book a custom tune if I had more mods, but not for a CAI. I am going with AM's JLT CAI and SCT combo. The SCT will come with a Bama tune written specifically for a mustang gt with JLT CAI.
