    01 3.8 NO POWER

    huge exhaust leak is a no no and will cause the o2s to dump fuel which can make it run awful the idle load is fine I would start by verifying the firing order is correct. If its stock it should be fairly simple to diagnose.

    2000 plus stall converter. Help

    everything about a stock setup is aimed for daily driving hence torque down low a large cam IMO anything > 300 duration is not going to make any low end torque so it will not be ideal especially for daily driving.

    Digital Tuning Tuner question

    im just seeing this i dont frequent here often the 2011+ cars don't require dyno tunes since they have on board widebands if you want the ability to switch tunes or update tunes without going some place then yes you would need some hardware to write the ecu a handheld can do that as is the...

    1997 cobra

    have you checked the ignition switch? while your cranking verify the check engine light goes off if it does you need to verify the injectors are pulsing and your plugs are firing. otherwise it sounds like you have a bad pcm which is very rare

    Eaton M90 on a 89 LX?

    a single eaton m90 is too small on a stock v6 supercoupe you will need 2 one on each valve cover and only then will you be in business. You'd be limited to about ~400rwhp though on an otherwise stock engine. Toss on a hci swap and you'd be in the ~585rwhp range.

    2000 plus stall converter. Help

    its always best to get at least a 3500+ stall for any of the 1994-2019 ford electronic control transmissions. The ecu controls the lockup so even though you may have a 4k stall converter it will still drive like stock when tuned properly. If your engine is basically stock otherwise with no...

    No start with spout unplugged

    the tfi ignition system is independent of the ecu. With the spout unplugged or even the ecu removed the ignition system will still function correctly. if it doesnt then you have an ignition issue between the tfi module, pick up in the distributor and its associated wiring to the coil.

    Automatic to Manual transmission

    you have to find the reverse gear switch on the trans and hook it up to your reverse lamps

    Ive pushed over 1400rwhp through a t56. As stated its a waste much better off going auto once your in the 700+ range.

    Low pressure switch

    i dont know what lp 3.0 is but if your asking low pressure shut off at 3 psi then no. The low pressure switch should shut off the compressor at no less than 20 psi minimum.

    2006 Mustang GT Knocking...

    that sounds normal do you have a tune on the car? that could very well be the cause of it as well. Can you run on the stock tune to see if the problem goes away?

    Engine Got a 93 mustang gt overheat on idle

    heres a much more accurate fuel injector chart http://www.efidynotuning.com/pre.htm the first thing you need to do is throw away that msd distributor and upgrade to a stock one over heating at idle is usually do to air trapped in the system. It doesn't take much to cool an idling engine.
