There is a significant learning curve to understand the tuning process for efi. There is significant information to process, things like MAP, RPM, temperatures, throttle position WBO2, and knock.
With that the EZ EFI takes away all that learning curve needed, but you won't be able to run nitrous like you mentioned in the first post. The EZ system can’t compensate for power adders being a self tuning speed density system. My motor is currently at the machine shop being reworked. When I put it back together I will be dropping my nitrous kit and slapping on an EZ EFI. The cost isn't all that bad when you consider that you can sell off a few items to lower the cost of the EFI. It would be a good chunk of coin to get the XFI system onto a carb car starting with nothing. Than you would still have to pay for tune time if you’re not up to the task. I dropped nearly a $1000 on 2 different tuners to get my turbo mustang tuned right. Could have been less if I took it to the second guy first.
