I don't know if the shop had AC on, but it was a cool rainy day, and he had a fan blowing towards the engine. I do not have the data on a disk, and i agree with Bollox, i will not be posting up the dyno results when the chip is installed. Only to other members on the forum via PM. I wish it didn't have to be like that, but since Scott is not providing any proof of gains, nor is he willing to help pay for the dyno... and i'm still paying $250 deposit for chip (you would think they would give me a bigger discount then that) that's just how its going to be.
