Made a few G-Tech runs...
Best run 0-60 was about 4.9s.
I felt like I shifted and started reasonably well.
I know G-Tech's are not terribly accurate, though, I was running about 5.4s in my old C4s cab and currently running about 5.0s in my C55. The Turbo feels WAY faster tha both.
Anyone have similar experience? Could my car be running sluggishly? If so, should I run any other tests?

I have the new G-Tech RR myself. In order to get the best results you need to calibrate the G-tech and enter in weight. You need to combine the curb weight of the car + your weight + est. 10 gallons of fuel + any other mods that may have added weight (i.e. stereo equipment, body kits, etc...!)
When you calibrate your device you need to make sure the rpms are accurate to your vehicle - have you done that part?
The G-Tech RR is actually a VERY accurate device. Suppose to be within 100th's of the V-Box and drag strip. But if you aren't calibrating or entering correct weight info then you will have incorrect data.
I use 3900lbs. The curb weight for the 996TT is 3388lbs. But then I added 225lbs for me, 50lbs gas, and another 230lbs for body kit, subwoofer box, and chrome techart wheels difference.
My 0-60's are all in the mid to high 3's. My 0-100 is right at 8.1 seconds consistently. However, I do have upgrades.
Anyway, hope this info helps!

I was reading the instruction manual last night, and my Gtech does not require a weight input.
The version I have is the inexpensive one. That could be why it is not accurate. Though it seemed to post fairly accurate numbers on my old 4s cab, and my current C55. Given this, I became concerned with the 4.9s run.

My Turbo weighs 3480 lbs with full fluids and no occupants (weighed on 4-pad racing scales). The only options that add/subtract weight on my car are power lumbar on both seats, floor mats, and sunroof delete.

Actually Joe is correct when it comes to the weight thing but I'd still make sure if there are any calibrations required that you do them beforehand.
Jean, as far as the 0-130 I got a 12.1 second time.

SMJ,
I've weighed in on the 0-60 thing before. An article I read regarding factory technique to get best times emphasized the importance of launch technique (something like 4000 rpm and a nearly sidestep clutch technique) but also pointed out that an error could be costly. In my ttX50, I've also been impressed by the necessity of an ultra-quick 1-2 shift, since redline comes up so quickly. In-gear acceleration is likely to be the best measure of comparative performance, since it eliminates so much driveline stress and shift variables. Somebody with a known-healthy engine might be able to give you the equivalent of 3000rpm-redline times in 3rd gear to best answer your question. AS

0-120mph in 10.3 also! I ran those when it was 98 degrees outside. I need to go and run more now that it's getting down to the mid 70's in the evening - love to see how much better the numbers would be when it's cooler outside. The car feels faster ever since we've dropped temps out of the 100's!!
Jean, helps to have 600hp I guess!
