Has anyone got a custom tune from any of these shops? How was your experience? Any info would help.

The Stratagy most Diablo dealers use is not ideal....especially on 03/04 Cobra's since the fuel table is based on throttle possition instead of load.
*Most* Diablo tuners use the fuel tables to dial in the A/F curve....which is basically modifying the pulse-width of the injectors to get the desired A/F curve.
The problem is that the 03/04 cobra fuel table is based on throttle possition & RPM. At a given throttle position & RPM you plug in the desired A/F. Most tuners modify the top TP values as this is what the computer looks at during WOT.
At WOT the A/F curve is tuned & flat on the dyno, but on the street if you're not going WOT (say 75% throttle), the A/F curve will not be correct unless the tuner spent a LOT of time dialing in the part-throttle (open loop) A/F curve.
Having said that, there are a few locals around here that run Nick Newton's tunes & they seem to be happy with his work.

I would take it to 93Pony if he dealt with the Diablosport. So far it looks like NEWTECH is the place but we will wait for more responses if any.Thanks fellas for your input

I just had John at Altered Speed tune my 98 Cobra. I am not supercharged, but I know he tunes everything (turbo's, NOS, superchargers). I am happy with my tune and he has a Mustang dyno. From what I have read mustang dynos are better for tuning then dynojets because they put a load on the car while tuning to simulate somewhat real driving conditions.
