Is there someone out there that has recieved the GM Roadster Tune and also has dyno graphs along with it? I'd like to see if people are gaining power near the 310 that they claim. Thanks
They surely wouldn't lie about it, other vendors with their own tunes claim similar numbers. And its pretty easy to get those numbers, doesn't take that long with hptuners.

I just wondering cuz he mentioned that the lowest gain was 24rwhp and the most was i believe 52rwhp. So i dont want to be one of the guys that only gains 25 more rwhp. If they guarenteed the 50+, then it'd be a no brainer for me to get it

No one will guarantee a certain amount of HP just because every car is a little different.
Location: Rosamond, CA - Home of Willow Springs Raceway
For example, the car that made "only" 24whp could've made more hp than normal on the stock tune. Hence the reason for the low gain. You would have to look at that cars dyno sheet to know for sure. Ask Martin (I think that's his name). He could tell you how much power that car made stock.

2lagues,
Martin has my Upgraded Wheel turbo.
I am hoping we can see the Upgraded Wheel turbo, the GMPP stage II and some additional tweaking by the tuner from GM Roadster.
I am really looking forward to some Dyno sheets and numbers.

I'm sorry for the ignorance, but is this the same tune as GM Performance Stage II tune?
Thanks in advance.
Don't apologize. These names are pretty similar and I could see where the confusion lies. The Roadster tune is an AFTERMARKET tune; however, the GMPP Tune is from GM and backed by them.
