That is one clean Mustang btw.
How tall are you?
I went and checked out the new Bullitt's and I really liked them, but I'm 6'1 and I felt way too cramped, especially coming from the F150.

to all the guys out there just reading and wondering if you should get a tune, Ill let you know next week after ford looks at it. and to the guys just making noise good for you dont really care bout your bs. if you buy a truck it works fine and install a tune and instintly runs bad with or without tune, more than likely its the tune.(thats all im saying) you can still state your opinion and i do know what im talking about. no matter what other haters says. there is a fallacy in thier logic(thier argument is wrong by definition)(ad hominem)cant just say im stupid and win argument go back to school.just do what you want. my .02

 

Sorry to hear that your tunes are causing you problems hope you get it resolved.

 

It's then, not "than".

 

You need to listen to the other members on hear as well they do know what they are talking about. However Thumper may think he does just dont listen to him he gets all worked up when something goes wrong with a tune Justin tune. I think he has a crush on him but just wont come out of the closet, thats why he drives a girl car... and posts in a truck forum.

 

You sir, are incorrect.

Thumper came into the thread with no hostilities... he offered help.

 

they are not giving advise, i told them i think the tune messed up my motor, i told them im taking it to ford to find out.and my opinion is dont buy a tune untill i find out . i woundlt buy one if i saw this thread until it was resolved. all they say is a bunch of useless crap, only a few have had a normal conversation like you. i said from begining ford will give us a definitive answer so just hold out till then but, i think i hurt thier feelings this forum needs less idiots like that i never posted since 2004 because to many people saying to much crap to people looking for help and only stating facts

 

thumper wasnt that bad he wasnt right either but the other annoying people like u shau are useless go away. get a life.

 

Well Black I hope your problem gets resolved a programmer may have done something or not either way I hope it get fixed for cheap. There are a few people that think that Justin can do know wrong but he is human and does make mistakes.

 

thats all im saying thanks for not being a moron like some others on here

 

Hey no problem take care.

 

It could have been a preexisting condition that was not quite to the point of failure, but with the increased power from the performance tune (they change timing, fuel schedules, A/F ratios, etc.) which now increases strain on the engine at the higher ends - PLUS you hitting WOT - it may have just been enough to cause a fatigued part to finally fail.

It happens, haven't you ever seen anyone in high performance racing throw a rod or pop a piston head...those guys are running high performance parts and still have failures from time to time, but most of the time they finish the race or run without any problems whatsoever. But if they had the slightest defect in the metallurgy of a component or ran a little too much compression/boost, things can get ugly. That's why they throw lots of $$$ to push the envelope of performance.

Same thing with your truck...let's say a part had a minor defect in it, but under "normal" driving circumstances it would've never been an issue as most drivers don't stress their engines under hard acceleration or long endurance at mid to high RPM's. It's practically loping around hauling air or groceries everyday, not meeting it's full potential. But then you add a tune, which now allows the engine to make more power and utilize more of it's potential, and then push it harder than before - both because of the tune's altering the parameters and the driver's leaded right foot enjoying the power gains - and that part that could've withstood several years and 100,000+ miles of loping now fails due to higher stresses.

Whose fault is it? The tuner, for making your engine able to utilize more of it's design power potential? The driver, for getting into it since he can, and enjoys a truck that's more awake than before? The manufacturer, for allowing a faulty part/batch of parts to get through it's quality control department and into your (and possibly many other's) motor? It's a little of all three, with 95% of it on the OEM if indeed it is a failure. That's why everyone on here is saying "take it to Ford", because if it is a failure they will fix it under warranty (you have 10,000 miles, right?).

It's their problem if something broke, your lead foot and the tuning just accelerated the issue. In fact, you should thank Justin for helping discover the failure sooner, since this could've prolonged into 80 or 90,000 miles and you would've been SOL and with a large repair bill. Take it to Ford in the morning, let them diagnose the problem, and then get back to us.....

 

miy hed hertz frum reeding theese posts

I'm not going to base my decision on the OP's claim that is probably just a fluke or freak coincidence. I'm researching which tuner to buy, and I'm leaning more towards VMP.

now to just convince the wife...how soon will I see a return on this investment if I tune with a 87 or economy? I'm just looking for something to gain MPG.

 

Let us know what happens.
