Default Another UTEC ?: Gains made over reflash

I'm not sure if anyone will even be able to answer this yet, as I don't think that that many UTECs have made their way into Z's just yet, but I'll ask anyway. Has anyone with the usual full bolt-ons (i.e. Intake / Plenum / Pulley / Ground / Headers / Cats / Exhaust) and also a reflashed ECU changed to a UTEC setup? What kind of gains were made over your reflashed ECU?

I ask because once I finish my bolt-ons, I don't plan on touching the car again engine-wise (I know, we all say that, right?), except for a tune. I won't really need to switch programs or tunes at all, so I'm thinking that a TS reflash would probably be good enough for me, unless the UTEC produces significant gains over the reflash, seeing as how it's twice the price (after tuning).

Thoughts? Opinions? Suggestions?

I know of 1 local guy, he made 13whp over his custom reflash with the UTEC. In the hands of even a decent tuner, UTEC > flash anyday...

Albert, he made 13whp peak? How about in the midrange? When i saw MRC's turbo dyno they made a nice 10-15% increase over midrange with a 5-10% increase at peak, and even more in torque. Did u see the same for your local guy?

Massive improvments in the midrange (20ft/lbs+), and slightly smaller gains up top (12-19whp). I would definately suggest a custom tuned UTEC over a reflash process.
