What did you do to your S550 Mustang today?!

wireeater said:

Not too bad at all. Stock exhaust came off easy with only 800 miles on it and it was built in June. I did it by myself. I just set my floor jack under the resonator so it wouldn't drop. Pulled it out from under the car and bolted up the xpipe/axle pipes first then installed the mufflers. I did have a little problem aligning them. I gave up because I just wanted to drive and hear them. I will work on getting them perfect on the weekend. I was tired and sore today doing the crap mostly by myself.

Awesome! Yeah, the stock exhaust coming down worries me since its all one piece but thanks for the advice! Much appreciated.

Finally went and got my 2015 GTPP tuned today by a local company called Injected Engineering local to the North Atlanta area.


The below graph is of my car on their dyno jet with the Solo Performance Mac Thunder catback and Steeda CAI (tune required) and stock tune. No other mods, car has 13k miles on it. Temp was about 85 degrees and humidity was 90%+. My car seems pretty strong for an untuned car putting down high 390's? These are SAE after driving 45 minutes over there and just a few minute cool down running Shell 93 octane.


Run 1 - 398RWHP/379RWTQ
Run 2 - 402RWHP/382RWTQ
Run 3 - 395RWHP/376RWTQ


After tuning I ended up with 415RWHP/386RWTQ on 93 octane. They did about 7-8 total dyno runs. I don't have the SAE corrected graph, yet. They are going to email it to me.



What are other folks putting down on 93 octane tunes and CAI?


I am going to run through 2 tanks of E85 and then head back in a couple of weeks so they can dial in that tune and re-dyno. The car has their flexfuel tune on it now since I can run e85. After I burn thru the rest of this 93 octane tank, I will be using E85.

Any feedback on Race Trac E85? They just opened up a brand new one, 10 minutes from my house

Those are VERY strong numbers, Todd...

Much better...

Thanks, Mike! I was curious as I have not watched numbers a whole lot except for the GT350 IM setups and the supercharged ones.

I cannot wait to get it to the track in October for the Steeda Pony wars and see how it runs in decent air with E85 in it

Those numbers aren't bad at all, in fact, pretty d*mn good. Can't comment on the E85 fuel, I don't think we have that around here.

NICE numbers.... Glad you posted as I was wondering if mine was close to others on here..

I recently had my '16 GT PP on a dyno to get baseline numbers...

I have an Airaid CAI, MBRP Street Catback and Bama 93 Tune, I eventually want to get an E85 tune as well.

My best run was..... 412 HP and 367 Trq.... It was on a Dyno Dynamics in ground Dyno....I was some what skeptical as the dyno over heated prior to my GT going on, I was car #25 for that day....

mustang week prep has begun! Except it started raining right after I got done priming the coil covers and starting on engine cover... damnit...

I bought a MBRP Street catback with h-pipe from [MENTION=10008]LethalPerformance[/MENTION] during their 4th of July sale (20% off), plus MBRP has a rebate going on! I ordered it Friday and it arrived on Tuesday Not bad for a holiday weekend.

It took about 1.5 hours to install while taking my time. It sounds SO good. Cold start video.

Possible stupid question, but is it ok to drive the car without the covers on? I ask because I don't get much time to work on the car during the week, and would like to just do it in my spare time over a couple days. Thanks!
