SD2 first start stage motor

[dank GN]

okay hopefully with in the next couple weeks I will be starting my stage motor . I'm going from a 235CID motor to a 281CID . What do you suggest doing with my initial tune Eric? I would imagine I would have to add quite a bit of fuel all around . Is there anything specific I should do ? I have 160lbs injectors,6871 triple ball bearing turbo ,226/226 solid roller , gear drive . If anyone has a bigger motor running a sd2 if you could shoot me a tune that I could modify but is working well that would be much appreciated thanks .

The SD2 doesn't have a displacement parameter. So to get the same effect, you reduce the injector size parameter the same percent as the displacement increase. Your displacement went up about 20%, so reduce your injector size parameter by 20%. That should get you fairly close, then the rest of the tuning is the same as before.
