Nick isn't the only one. There are plenty of diesel and gas tuners that have rebranded AutoCal.
It's not like Superchips and SCT at all. EFILive doesn't sell tunes, and we don't offer tuning advice, we sell Custom Tuning software and provide software support.
Many of our professional tuner customers expressed problems with mail order tuning - cost of ECM's, it was hard to dial in a customer remotely, fine tuning was based off a customer trying to explain the problem (ie no data logs), time frames for sending/receiving mail, customer doesn't keep a code clearer or have the ability to return the vehicle to stock etc, etc.
Simply put, AutoCal eliminates those issues. The handheld market just grew significantly. Master tuners now don't need to be master software and hardware developers as well.
Cheers
