I have done several modifications to my 2005 Sentra Spec-V and really need a tune. (AEM CAI, APEXi N-1 exhaust, Megan Racing Header w/o pre-cat, Fidanza lightweight flywheel, OBX lightweight crank pulley, Greddy stage 2 quick release clutch, NGK Iriduim spark plugs, VIS Carbon Fiber hood) I was thinking about getting a nice engine computer like an Edge or something but I'm having trouble finding a computer for my car.

Any advice?

From what I heard through my mechanic is that the ecu for specs can't be tune unless you do a piggy back
There's a stillen qr-pro it's a piggy back system but allows you to control your air/fuel ratios
There's also an apexi safc
They go for around 500+

Thx

Thx for the advice but u can't reprogram the stillen one and I hear about the Apexi SAFC 2 on the forums. I was wondering if the Apexi SAFC Neo will work as well? I'm interested in getting the larger throttle body a with a spacer and I read that the only way to bring down the idle with it is to get the fuel management computer I mentioned before. I have only read about the Apexi SAFC II and didn't know if the Neo works as well and that I haven't read about it yet just because it's newer. Any advice would be greatly appreciated. Thx

yea, the stillen one isnt worth the money, unless its free

the afc2 should be enough to accomplish what youre doing, without boost, not sure about neo, never used or seen one in person. some other tuners to look into would be like osiris and uprev. go talk to the people on b15u.com there's a lot more tuned and boosted guys there with great info. there's also write-ups for the vq35 tb and how to adjust throttle plates and secondaries, theres info there for osiris and uprev as well.
