Cobb vs UpRev

semtex

Well, there's a lot more to tuning than just tweaking the AFR. You can tweak the ignition timing, for example. But like I said in my previous post, I'm a little confused myself at this point. If you can get a dyno tune with both UpRev and Cobb, then is one really better than the other in terms of hp gain? I would think that the answer is no, as long as both give the tuner an equal amount of control and flexibility over all the pertinent parameters. I'm no expert on tuning though, so if I'm wrong, someone please jump in.

I actually talked to Sharif at Forged last week and gave him the green light to order in a Cobb unit for my Z so that he can dyno tune it. I want to make sure I'm not shooting myself in the foot. If I find out several months from now that Sharif would've been able to get even more hp out of my car had we used UpRev instead of Cobb for the tuning, I will not be a happy camper!
