I know other years apply but thats the car i deal with, well to put it simple we put the diablo tune on the cobra because of the billet flow pulleys JBA mid lenght headers and 3 inch exhaust system and thought every thing was fine but when we dynoed the track car we threw the cobra on for fun

What we found was a massive fule issue the fule stays at about 11:1 (which is low) and when it gets to about 4K rpms it drops to 9.5:1 to 8:1 and the power curve goes absoultey nuts

we thought there might be a problem but couldnt put our finger on it but never dreamed to see that on the dyno were having a SCT tune put in it by a tuner next month

our HP was 392 at the rear wheels, hard to say at what RPM though as the car went nuts trying to compensate for the fule issues intresting enough the computer calcuted 505 HP at the crank which doesnt seem right either but with the fule going to crap and the ECM trying to compensate whos to say

Anyway this is our exprince with it, its robing of us HP at the wheels we think we might hit 420 at the wheels after the SCT tune which we have on the track car and customized it to run in our drivers comorft zone

SO beware of diablo if you have this run your car on a dyno to make sure your fuel is alright cause ours suck with it.

I had a diablo for my 07 C6, and IMO they are not worth the money when you can easily get an SCT instead. I had a chance to get a Diablo Tuner somewhat cheap for my GT, and I went with the SCT for more money because of just how bad I felt the Diablo was. I ended up getting the car dyno tuned once I installed the Procharger and sold the Diablo.

Useless IMO so I agree with ya.

Are you sure it was the tune and not the tuner? You have to realize that a tuner like that a lot of times is like a liason. It's just getting what you want from one spot to another threw a type of communication is all. I prefer SCT because the dyno I go to uses SCT, but you can't just say a tuner is bad because you have a bad tune.
