Over the summer (because of funds) I am planning on getting a PPE stage 3 or 4 trans installed with a high hp programmer and my original plan was to keep my truck stock in the meantime but I borrowed my dads hypertech in level three and I now I don't think I will be able to stick to my original plan. I want to buy a predator in the meantime and was just wondering how concered I should be with a stock tranny for about 7 months. The predator will probably be left in 85 for 70% of the time 65 for 30%, and I would like to use 120 for a few occacional races. Is this okay with a stock tranny?
