I just picked up a 2011 roush stage 2 for a great deal was not even in the market. brand new sitting on the lot. I was at the dealer gettting the tags for our new ecoboost f-150 and was looking around and the next day the sales guy called and told me what they would sell it for and that was it. I was impressed with the 5.0 in the stock form, But as i searched and watched videos i just got the itch and that was the end. Did the install in the garage and it was pretty straight forward. If you have any mechanical abilities and can read it was simple. The grinding wasnt bad either. I did the grinding before the kit was here to save time. I dont hurry one bit when doing something like this and i bet i had about 15hrs into the whole process. Had a startup tune from evolution and had john lund tune it on there dyno after everything was complete. On there mustang dyno it did 559hp and 486lb-ft at 7.5 psi. I did magnaflow offroad x and borla s axleback at the same time. The car is insane now. enjoy the install pics. i had a blast with the install.
