ok i have a greddy e-manage blue that was not installed yet. my turbo project is going to happen in a few weeks. i was wondering if it would be easier to sell the e-manage and get an apexi safc2 instead. im going to be running a 7 pound spring in the waistgate but if i get a boost controller would it be easier to change the boost on the fly with the e-manage or the safc? im saying so i dont have to pull out the laptop and change the tune, or do i just need the same tune and i can run higher boost with it(i dont know anything about this stuff yet. but im learning). money is an issue for me so i cant just dish out the 500 bucks for the profec eo-1 for my boost controller. just let me know what you guys think!
