I went to Pro Dyno today and had my 4.0 with ProCharger tuned. Let me tell you, the custom tune makes a huge difference! Throttle response is crisp, shifting is much, much better. Now I can mash the gas with no worries. I really wish I could drive a 3.7 to compare but I'm pretty happy with what I have now. But it certainly cost a few bucks to get there. :-)

Here's a video of the first pull and a pic of the dyno sheet.

You're welcome. Hopefully this will help you, as well as others, decide your path to Mustang happiness.

I am a giant giant fan of the 3.7 I absolutely love it!! It responds very well to most mods. I know from people and reviews about it. But ultimately i would love to have a gt.

I dropped the stage 2 procharger into my 4.0 about 3 months ago and I LOVE it.......it's 150% all about getting a CUSTOM TUNE......take it to a RESPECTABLE shop and let someone with TONS of dyno experience tune it for you. Asfar as the rearend goes......the stock rearend will be able to handle it. But i would absolutly recommend getting some high-flow cats or an O/R X pipe. Me personally, i love my car and would not get rid of it for anything........and it draws TONS of attention. Taking home alot of trophies this past year and killed alot more cars. It's nice to get your run of the meal "why didnt you just buy a GT" guy.......but it's even better when you beat him in his car on the track AND at the show. At the end of the day, it's all about BUILDING YOUR CAR.......I've been to atleast 1 (sometimes 2) car shows a week since this past March and I have more respect for guys who have taken nothing and made something than the guys who buy a car with 300+ HP who have no clue how to drive it.

......you WILL need some good tires. The first week I had my procharger installed, I had to switch out my Nittos for my stock rims/tires due to a nail.......was not fun at all, unless burning through a set of tires without actually moving is your thing
