How Much Power Will These Mods Yield?
780s sounds about right for your goal, I also have 780s for my GT30. On my experience its easier to tune if you do the math and only use the ones you really need or a little bit more than what you need, unless you are planning more mods in the future, dont go with huge 1000cc if you only plan to run 22psi on a 50trim, it will be a PITA to finetune! Any small change on the map will change a lot in the AFR. Just my experience. But ask Eric...
