How do you compare Edelbrock to the Maggie Heartbeat.
'16 Z51 A8

They are pretty equal since they are both based on and use the Eaton TVS2300 supercharger.

FWIW, the stock Edelbrock tune on my '13 Mustang GT was horrendous. It had horrible surging and was almost undriveable. I got a Brenspeed e-mail tune, which also added HP, and all was good, but it voided the Edelbrock warranty.

Sorry to hear about your issue did you contact Edelbrock? We have sold and insalled about 55 units since Edelbrock has released the E-Force Supercharger and have not had one tuning issue. If the install of the software is not followed correctly files can get corrupted that may cause some issues. We've installed these units on Camaro's Corvette's Mustangs and Hemi's with no issues at all.
