No A9L does not have that problem. What ECU do you have now? Do you even need to replace the computer. If you just want an injector and MAF upgrade get 24# injectors and a Pro-M Meter. The injectors are 219.95 through summit the meters are usually like 229.95. 24# is all you need. Seeing as you have heads, cam, intake 24# would be perfect, now if you had some more compression like 10.5:1 or higher I would say go with 30#. Hope that helped.
