    Holy ****!!!

    Let me start out by saying I'm writing this review from my iPhone, with my 18 month old daughter climbing all over me. Well, that said, I love this mod. I bought my 13 ROUSH stage 3 with the phase one supercharger in it from the dealer. It was nice and fast. It still wasn't fast enough to match the sticker price though so, I had to upgrade to the phase 3 supercharger. Within a month I got a gt 500 rear end (cuz I broke the stock one, don't ask) the phase 1 to phase 3 supercharger upgrade and a one piece aluminum drive shaft all from AM. I also bought an MGW short throw shifter (from MGW) cuz as we all know the stock one is garbage! Well I work at night and sleep during the day so, once I had all my parts my buddy had me drop off my car at his place where he installed everything, I mean everything within a few hours using basic hand tools. The PCM does require custom calibration by ROUSH so, you must remove it and ship it to them so they can tune it for you. It cost 80 bucks to ship overnight, but ROUSH was supposed to cover it, I just forgot about it literally until now, well ****! Anyway. From start to finish it was only three days. Roush is fast with that turn around. I'm in north Florida by the way. The performance gain was substantial and immediately noticeable! I've yet to have it dynoed due to the lack of shops near me (that I know of), but holy **** is it much faster now. As far as track time goes I'm sorry to disappoint anyone, but my work schedule doesn't really allow me to go, plus the only one near me is only an 1/8 mile track. Now, this isn't just my weekend car, it's my DD and as far as drivability goes it's awesome. It isn't noticeable until you get on it (the throttle I mean) and when you do, hold the **** on to her! My average MPG right now is overall since I bought the car, 13.9 MPG and my current average MPG according to my car is 14.2. I do drive like a maniac though, if that offends you well, I'll just go on living my life. Well, I hope this review was somewhat helpful. Once I dyno my car I'll post an update on my current hp/tq.
