335xi vs Mustang 3.7 , something wrong with my N55 xi
Hi guys,
I did a test with my cousin 2014 V6 3.7 mustang this morning . Mustang : Bama Race Tune 93 octance Airaid Cold Air Intake BBK 73mm throttle body Ford Racing 4.10 Gears 335xi : JB4 93 Octance Map 2 Bms charge pipe Active autowerck downpipe Active autowerck intercooler sport version First run from the 20 roll. I switch to map 0 because i believed with map 0 and all other support mods are good enough to handle the mustang. However the mustang hang around with my xi from 20-70. I only won half car length until we hit 100. Second run from the stop. I switch to map 2. Im about half car from 0-60. then from 60 - 100 im pulling far but slowly. I though all those mods are enough to hang with 5.0 GT not the 3.7 Mustang. Is it something wrong with my N55 xi ? Please enlighten me . Thanks |

From my understanding a FBO n54 will maybe hang with a 5.0. Your n55 xi will not. The all wheel drive robs power and the n55 doesn't respond as well to mods as the n54.
But why not throw the jb4 on the 18.5psi auto tune map? |

You're almost FBO from the looks of it. Dci and exhaust are minimal gains so you don't have much to gain without e85/meth. But it takes a large hp difference to really put lengths on someone quickly. E85 would take care of it running an e30-e40 tank most likely. I've not run e85 in my personal car as there's no stations around but have driven one and the power bump is pretty significant. |

I should have bought the "i" not "xi" . I was consider the E85 , but to drive around and find the gas station that has E85 is not so convenience. Next stop maybe Meth kit for my car .
Thanks a lot for helping me Hokie. |

On map 0, the race seems about right. He was probably making more power than you when you're on map 0 considering the mods he has, plus his car is lighter.
On map 2, though, I think you should've raped him. |

Is this post a joke? From my research a 2014 Mustang V6 with Bama tune and 4.10 gears is going to run about a 13.6 in the quarter mile. Best case scenario is a 13.3. My 2009 335i xdrive with catless dp's and FMIC upgrade ran a 12.3 114mph. With my E40 map I ran a 12.1 @ 116mph. This is not even a race. My dad has a 2014 Mustang GT and I rape him in from a roll and severely rape him from a dig. My cars 0-60 is 3.7 seconds. No freaking way a V6 stang can even be discussed in the same conversation as ours where performance is concerned. I say get your car checked or maybe driver error perhaps.

I ran a stock 5.0 from a low 10-15mph roll and we were neck and neck, both pulling slightly on each other as we went back and forth. All I have is a Cobb Stage 1 and DCI. A tuned 335 should mop the floor with a v6 stang |

Yes i have N55 model, as Hokie said it not response well to mods. To :"saviorxi" im not joking man, it is real. Im so sad the N55 xi is not that good with almost FBO.
Yesterday i test it again with 2 different car . A stock new model Camaro RS and new 328i. It was an easy walk on Camaro . But, when i test it with friend new 328i with slightly mod. again my Xi is not pulling far from him, it just one and a half car length a head from 60 to 130 |

I have a 335xi n54 and when I ran jb4 I used map 5 all the time. It auto tunes. You can toss some e85 in there and wake it up too. 3-4 gallons to start. Won't be a big deal if you can't find it from time to time either due to the low % and the auto tune. I may be wrong but that was how I ran it and it worked great!

Go to JB4 website, or try here if the link is allowed:
http://www.n54tech.com/forums/showthread.php?t=21269 Basically you have a data logging capacity. I do not own a JB4 so others may chime in. Basic idea with all these tunes (I have Cobb) is you install them, ride around for a bit to make sure nothing seriously messed up is going on, then do some hard pulls while logging a list of key engine parameters to make sure everything is OK. If you cannot beat a V6 mustang I guarantee you something is messed up. Not sure about if JB4 can do this but also pull engine trouble codes. You can do this on Cobb or with INPA. See if you are getting misfires etc. Bottom line though sounds like you need to read a lot more about what the JB4 does and how to use it, like which map does what, then get into reading codes (if any), then logging some pulls. Often the first thing happens is misfires due to old plugs. |

BTW, there isn't much performance difference between the xi and the i model. The XI launches harder due to traction (faster 0-60). The I losses a little less HP (only talking about 15 HP or so) due to RWD (It catches back up to the XI by the end of the 1/4. The XI would also be better coming out of corners in a track environment. Last edited by beetle6986; 07-09-2014 at 01:30 PM.. |

We have a guy here who can't drive all that well running 13.20 in a 6AT 3.7 with exhaust and tune only (dude in OP has TB and gears). The gap between the 3.7s and 5.0s is atypical of the traditional V6 vs V8 Mustang matchup. Still a reasonable gap but they aren't slow.
