My day started at about 10:00 yesterday at RealSpeed Automotive on Long Island in NY. Dan Carlson, the owner know his Mustangs inside and out - he was a lead designer for Steeda for years and knows everything there is about fine tuning these things.

He started taking everything off and completely hollowed out that rear. Then he started reassembling the gears and the TT. He meticulously measured and remeasured and then we brought it down.

We reflashed my SCT with the new gear ratios and upgrade for the software. But - oh oh, the car kept throwing error codes now with the new software upgrade and gears. When returning car back to stock the Error codes were gone. So after doing about a half dozen changes, we tried using a brand new Tuner out of the box, just in case something went wrong with mine when upgrading the software. But, still had the same problems. We then called SCT, but Tech support had already closed. Dan never gave up and never made me feel like it was even bothering him. He is a true diehard Mustang afficonado and would only let him work on my pony - ever. It was already almost 7:00 and Dan decided - lets try readjusting my tunes with the gear rations and use the old software to reload - WHALLA - No trouble codes. Seems that the new software may have a bug in it and he is looking into it with SCT to see why. I'll keep you guys and girls posted.

That's where the fun started. We decided to take it for a spin and see what difference the new tune, gears and that TT made. I told Dan that he should drive it. This was the first time he got to be in the drivers seat in my ride and let me tell you.....

WOW ... We figured lets test out the TT and we just hit the gas and lit those tires UP!!! It was amazing then the 3.73 kicked in and pulled like a b!i#h! He said he was very very impressed with it. He didn't think that the 6 was that powerful and that it definitley felt like it should be sub 6's for the 0-60. We figured we would Dyno it next time and see the times and final hp.

It was just crazy how the TT kicks in and the whole car feel 500% more solid in the rear from take off - through out. The 3.73 give it such a pull that it really feels like it could knock around almost any stock v8 prior to 05! Not that I am knocking the V8's but it is putting down some serious pull and coming from Dan, He was "very impressed" with what we had done. The tune also shut off the torque limiter and just feels like the car has no throttle lag at all. I also got to test out the TT last night since some roads had some wet leaves and wet spots and it was unreal. It grips and makes a night and day difference from the one legged hopping I was doing in the past.

Definitely well worth the money! BTW, I also met a guy that was having Dan install his Roush supercharger on his V8 Roush and we got to talking for a while. His car was sweet and got me even more convinced that this 6 needs a supercharger next. Dan was at SEMA earlier this month and is still waiting to see which companies are going to offer the best S/C. Paxton has the Novi1200, but seems that it is only available through Shelby for the v6, so we'll see if something changes there and what else happens in the next few months.
Next scheduled mod - S/C for Spring )))

Figure with S/C we could be running 0-60 times in the 4'sto at the least mid to low 5's!! and quarters in low 13's high 12's. Not bad for a V6... I would just like to see the look on a 350z [:o]

Lovin my stang more and more each day --- Have yourselves a great Thanksgiving , and thanks again to Dan !

That is awesome!!!! I just had mine done last week and you are right, its hard to believe its a 6 under the hood. Try taking a hard corner, with power to both wheels you will feel the difference.

And thanks for the tip on the tuner, I am getting ready to switch to SCT.

screamin...

Nice.. I am a fan of the 3.73 instead of 4.10s... they seem to work well in the 6. The S/C is definatley in the game plan for my little pony. I am still waiting to hear from the CEO of Lysholm in Sweden on the issues they were having with Whipple before I see what's up. I prefer the Twin Screw and Whipple is da' ****, if they can only get their issues sorted out with Lysholm Technologies.

Happy Thanksgiving and Enjoy the Stang!

Thanks for the responses

Thanks guys, and girls....

I can't say enough how I love the new setup, and thanks for all the feedback and the help that this forum and its members had making my decisions. After having done alot of research I have to say that the 3.73 were just right and am convinced that they will take to the s/c the best. Also the TT will be able to handle the power generated by the S/C and keep both wheels to the ground on takeoff.

Taking turns feels like it just wants to grab and not let go of the ground. I can definitely see and feel what a difference the Detroit TT makes. It almost feels like I have a new set of tires with the amount of grip it gets, and not to mention it feels CRAZY when I stomp on the gas from a standstill - the whole rear trembles and I could swear it takes me back to the old 5.0 days. Like I said even Dan who like many other Mustang pro's are really used to the V8's said he was so impressed at how the mod's worked on the 6 , and that it definitly was not the old school 6'ers anymore.

Jen, keep us up to date on anything you hear about the S/C. I am hoping to be able to get the Novi1200 that is going into the shelby cs6, but it seems that currently they are only selling the v6 model through Shelby (Paxton division)... I think that spring time will have a couple of new players in the arena and give us all a little bit of a selection

All in all , I am quite thankful for my 4.0 ---- Happy Thanksgiving to all !!!

We beat it, but not "ripping" it. We drove it around a little for a while and then did some harder passes. I put on almost 100 miles before really stomping on it yesterday. The shop is about 25 miles from my house and work is another 25 in the opposite direction, so i rack up miles and break in pretty quick.

btw - also used synthetic fluid in the rear instead of conventional.

and you can really tell from just tapping the gas that the 3.73's have a whole different feel and response. Also it had been raingin all day and we had alot of wet spots we could test out the TT without having to even go half throttle.

Otherwise - who am I kiddin, I still would have been hittin it - Just like everyone else - I give in to temptation - that's probably why all of us are here and constantly modding

Gears and diff are one of the best upgrads you can do. I am amazed at the difference. I was mostly good on break in on mine....though I punched it two times just to test it out. Tomorrow my car goes in for shim adjustment and re-oil now that they are broken in.
