I am researching it as we speak! I have Mega squirt 3 on my 73 Cuda and love it but it was complex to install. Read I got frustrated. I am not as strong electrically as I would like. The whole EFI scene is evolving at a rapid pace and I think personally that Holley is out front with user friendly aspect. Please let me know how you do with yours as I am still a long way from needing to make that decision. Translated I am out of money!! I need to heal up a bit here.
