Did you ask Terry about this?? I was ready to buy this tune; however, the above dyno is very disturbing to me. I am anxiously waiting to see when Terry will respond to this information. It seems that the shop has contacted Terry over 2 weeks ago about this.
Is this your install? In only have the Stage 1, but like I have written before, it make a world of difference even though it does not have the attributes of the stage 2 tune. I notice, like the OP said, instant power on when driving. There is some, I wouldn't call it pronounced lag, but a softer take-up that I experience in many cars. I talk about it here.
