    1987 LX, looking to go Holley EFi!

    Skip the 24s those are the most useless injectors ever made. The minimum injectors anyone should run is siemens deka 80s. They have BETTER than stock flow control and are ULEV certified. They are also OEM ford injectors. Good from 0hp up to 800hp. Theres absolutely no down side to them and...

    TunerPro RT

    There's plenty of QH's out there and more to go around. I wouldn't be too concerned about finding one if you need one.

    Odd EEC-IV Adapter Found between ECU and 60 Pin Harness

    yeah much has advanced since the 90s in the EFI arena The worse part about that whole contraption is that it's only worth a connector and about 30 cents worth of resistors which was about equal to 8 cents back then. They made a fortune selling them for what they did ~100x the cost.

    Tuner chip (I think)

    You hit the jackpot! Thats a moates quarterhorse. Its an enulator that turns the stock ecu in to an aftermarket standalone. custom tuning software is a free download http://www.efidynotuning.com read the QH out as a 4 bank file and post it on that forum to get the tune or tune(s) sucked out...

    Fuel Fuel Pump upgrade on mild 5.0L

    genera rule of thumb is your return should be the same size as your feed if they are the same length all the fuel systems i do i mount the regulator next to the tank so the return line is very short. But that requires an aftermarket regulator.

    No More Offroad Mid Pipes?

    I can tell if a car has cats or not just driving behind it. I cant tolerate being in the vicinity of a vehicle with no cats before it affects my breathing. We build turbo coyotes that make 1000+ rwhp on the stock cats.

    2000 Mustang GT 4.6L Code P0302 (misfire on cylinder 2) CAN'T SOLVE!!!!!!!

    Verify the injector wire and coil wire are indeed for cylinder 2 and cylinder 3. If those injector or coil wires were mixed up it would do the exact same thing.

    Engine 87 LX won't run after warmed up

    pinched fuel line will restrict fuel flow and cause lean out at wot which is the #1 cause for engine failures and a perfect way to grenade the engine hence why you should never go WOT when you have mechanical problems or if the vehicle is not running correctly. As you stated it pulled hard...

    3.8 to 4.6 swap

    yeah if you have the budget for the tfs heads that a simple +100rwhp bolt on. You should use tfs specific cams though. And you will need to use GT supercar followers. With the tfs heads you will need at least 30 lb injectors minimum and an upgraded maf. Best bet is to toss siemens deka 80s...

    Question/Clarification for 2008 Mustang Mach 1

    Car is worth about $8,000

    New member in Florida. I have 2004GT and 2005coupe. 2005 has an electrical problem that Ford can't find.

    radio coming on and off would typically mean a bad ignition switch or the radio is shorting out internally which can kill the battery as well

    fuel pressure adjustment 19 or 30lb injectors.

    93 doesn't use a map it uses a bap but you don't need it the 93 ecu is a downgrade from the 94/95 ecu. A lot of people did that down grade years ago because they had sub par tuners. No point in going to 19s or swapping mafs if all works now. Best bet is to dial in what you actually have...

    TPS Voltage reading

    As long as the tps is between .7 and 1.25 volts at closed throttle its set perfect. make sure the key is on when your testing. And be sure you use the wires at the tps for power and not the battery as it will be skewed.
