I have ssv kenetix intake man, aem cold air intake, helix cat deletes, greddy evo TT catback, on a 03 z. I'm wondering what kind of numbers did anyone put down with this or similar setup, and let me know if i could benefit from a engine management, or just a reflash. I plan to turbo my car over the winter this year, i only have 40k miles on engine, so i think it's a sound motor. Which management system would be most ideal for my setup now, and for when i plan to switch to turbo so that i don't buy a tuning setup that can't convert when i turbo. I'm thinking either going with greddy twin kit, or aps!
