This might be a stupid question, but for a N/A Z, other than the rev and speed limiter cut, what can the e-manage ultimate do?? Would it be a good thing to have??

 

Depends. If you are stock, you don't really need it. not sure it will do anything, maybe a couple HP.
It's a much better idea when you have a few NA mods and want to tune the car to really take advantage of them. It will net some few more HP, and makes sure the engine is running like it should.

 

well, i have APS test pipes coming in. Do you think it would be worth it with just that mod?? I also plan to do headers and exhaust in the next 4-6 months too. What you think??

 

if you plan on going all out on your bolt-on's then I'd suggest some kind of ECU upgrade/tuning. otherwise you won't be taking advantage of all the power those bolt on's might otherwise give you. also you might end up running lean which isn't good and needs to be corrected to avoid any long term problems. if you plan on ever going FI then you def should invest in a good piggyback/stand alone ECU, if not you could also get away with doing a reflash with AAM or technosquare, however I wouldn't recommend it unless you'd be able to bring your car to them so they can dyno tune it.

 

hmm .. just get a reflash ... i'd rather have EU for FI or if i strokerd my Z and cammed it !!
