5.0HOBOMB

Hi all! I had some questions on dyno-tuning my 95 GT with AODE. My car has several mods but im not sure it was ever tuned for those modes it had before I bought it. I've also done some modes myself. The mods are as follows:
BBK CAI
BBK shorty headers
off-road H-pipe
MAC catback
AODE shift kit
3.73 gearing

I have been getting some codes due to check engine light and the codes are as follows:
fuel system is lean
speed sensor malfunctioning

so due to the codes and the mods, I assume my poor stang is asking me to do a dyno tune but I wanted to make sure this is correct. How much would a dyno tune cost on average???

Well, I dont really think its necessary for you to tune it. Would it help? Yes of course it would. Around here, Central Illinois. Anderson's Ford Motorsports in Clinton charges 210 for the first hour and like a 100 for every additional. If you have plans for future mods i would definetly wait until they are done.

Yeah, a guy at the local mustang performance store said that the tune is uncecessary and very expensive, but I just dont know how to get rid of the code. He said there are numerous reasons for the computer to pull up that code, but i just thought maybe it was the intake and catless exaust. So can anyone suggest what could possibly cause this code to appear??? Some people have suggested it could be injectors, or vacuum hose leak, timing etc.
any help is appriciated

get a set of injectors and a bugger fuel pump, also a maf thats calibrated for the injectors, with a list like that, there's NO way you would need a dyno tune. i needed one on my 88 but that car, i have about 5k worth of parts on with a 331 stroker kit. i would not recomend a dyno tune just yet. try the injectors and a bigger fuel pump with the right maf first off. once you have injectors to support the car that should rid you of the lean code

WRONG!!......HIS FACTORY 19lbs injectors are more than adequate to support his small list of mods.............to the op we need a code number to isolate LEAN CONDITION TO A COMPONENT.......such things as exhaust leaks, faulty HEGO sensors, weak fuel pump, restricted fuel filter and vaccum leaks and bad maf can all cause lean conditions to arise ..what was the code number??

redpony88

thing is who knows if his injectors are clogged up, filter, pump not pumping so well. but you're right the 19's are fine for that list, more of a suggestion as a additional upgrade since most will go for 24's off the bat.
check for vaccume leaks, one way you could try is using a can of brake clean and spray it around the engine, it's one way we check at the dealership. alot of the time the lines that run behinde the manifold will rot and fall appart, at least thats what i've run into on alot of the 5.0's around here.
