The canned tune is fine, just super conservative. You're right about too much fuel and not much timing causing the backfiring issues, but this is a safety net Sam has to do since each car is different. Some cars like more fuel than others, some like less. Same with timing, ect.
A custom tune will net more power and torque, clean up the driveability, air/fuel and help your MPGs. It will feel like a totally different car, if it's tuned by someone competent with UpRev.
